FAQs
1. What is the difference between a strong acid and a weak acid? Strong acids completely dissociate in water, while weak acids only partially dissociate.
2. How do I calculate the pH of a strong acid solution? Use the formula pH = -log[H+], where [H+] is the concentration of hydrogen ions.
3. What is a buffer solution? A buffer solution resists changes in pH upon the addition of small amounts of acid or base.
4. How does the Henderson-Hasselbalch equation work? It relates the pH of a buffer solution to the pKa of the weak acid and the ratio of the concentrations of the weak acid and its conjugate base.
5. What is the equivalence point in a titration? The equivalence point is the point in a titration where the moles of acid equal the moles of base.
6. What are some common indicators used in acid-base titrations? Phenolphthalein, methyl orange, and bromothymol blue are common examples.
7. What is the Arrhenius definition of an acid and base? Arrhenius defined acids as substances that produce H+ ions in water and bases as substances that produce OH- ions in water.
8. What is the Brønsted-Lowry definition of an acid and base? Brønsted-Lowry defined acids as proton donors and bases as proton acceptors.
9. What is the Lewis definition of an acid and base? Lewis defined acids as electron pair acceptors and bases as electron pair donors.

| acids bases worksheet i answers: Microscale Chemistry John Skinner, 1997 Developing microscale chemistry experiments, using small quantities of chemicals and simple equipment, has been a recent initiative in the UK. Microscale chemistry experiments have several advantages over conventional experiments: They use small quantities of chemicals and simple equipment which reduces costs; The disposal of chemicals is easier due to the small quantities; Safety hazards are often reduced and many experiments can be done quickly; Using plastic apparatus means glassware breakages are minimised; Practical work is possible outside a laboratory. Microscale Chemistry is a book of such experiments designed for use in schools and colleges, and the ideas behind the experiments in it come from many sources, including chemistry teachers from all around the world. Current trends indicate that with the likelihood of further environmental legislation, the need for microscale chemistry teaching techniques and experiments is likely to grow. This book should serve as a guide in this process. |

| acids bases worksheet i answers: A History of the Egyptian Intelligence Service Owen L. Sirrs, 2010 This book analyzes how the Egyptian intelligence community has adapted to shifting national security threats since its inception 100 years ago. The author argues that studying Egypt's intelligence community is integral to our understanding of that country's modem history, regime stability and human rights record. It is clear that intelligence agencies are pivotal to understanding the nature of many Arab regimes and their decision-making processes, and there is no published history of modern Egyptian intelligence in either a European language or in Arabic, though Egypt has the largest and arguably most effective intelligence community in the Arab world. Starting in 1910, when the modern Egyptian intelligence system was created to deal with militant nationalists and Islamists, the book shows how the security services were subsequently reorganized, augmented and centralized to meet an increasingly sophisticated array of challenges, including fascism, communism, army unrest, Israel, France, the United Kingdom, conservative Arab states, the Muslim Brotherhood and others. This book will be of much interest to students of intelligence studies, Middle Eastern politics, international security and IR in general. --Book Jacket. |
| acids bases worksheet i answers: Aqueous Acid-base Equilibria and Titrations Robert De Levie, 1999 This book will give students a thorough grounding in pH and associated equilibria, material absolutely fundamental to the understanding of many aspects of chemistry. It is, in addition, a fresh and modern approach to a topic all too often taught in an out-moded way. This book uses new theoretical developments which have led to more generalized approaches to equilibrium problems; these approaches are often simpler than the approximations which they replace. Acid-base problems are readily addressed in terms of the proton condition, a convenient amalgam of the mass and charge constraints of the chemical system considered. The graphical approach of Bjerrum, Hagg, and Sillen is used to illustrate the orders of magnitude of the concentrations of the various species involved in chemical equilibria. Based on these concentrations, the proton condition can usually be simplified, often leading directly to the value of the pH. In the description of acid-base titrations a general master equation is developed. It provides a continuous and complete description of the entire titration curve, which can then be used for computer-based comparison with experimental data. Graphical estimates of the steepness of titration curves are also developed, from which the practicality of a given titration can be anticipated. Activity effects are described in detail, including their effect on titration curves. The discussion emphasizes the distinction between equilibrium constants and electrometric pH measurements, which are subject to activity corrections, and balance equations and spectroscopic pH measurements, which are not. Finally, an entire chapter is devoted to what the pH meter measures, and to the experimental and theoretical uncertainties involved. |

| acids bases worksheet i answers: Ocean Acidification National Research Council, Division on Earth and Life Studies, Ocean Studies Board, Committee on the Development of an Integrated Science Strategy for Ocean Acidification Monitoring, 2010-09-14 The ocean has absorbed a significant portion of all human-made carbon dioxide emissions. This benefits human society by moderating the rate of climate change, but also causes unprecedented changes to ocean chemistry. Carbon dioxide taken up by the ocean decreases the pH of the water and leads to a suite of chemical changes collectively known as ocean acidification. The long term consequences of ocean acidification are not known, but are expected to result in changes to many ecosystems and the services they provide to society. Ocean Acidification: A National Strategy to Meet the Challenges of a Changing Ocean reviews the current state of knowledge, explores gaps in understanding, and identifies several key findings. Like climate change, ocean acidification is a growing global problem that will intensify with continued CO2 emissions and has the potential to change marine ecosystems and affect benefits to society. The federal government has taken positive initial steps by developing a national ocean acidification program, but more information is needed to fully understand and address the threat that ocean acidification may pose to marine ecosystems and the services they provide. In addition, a global observation network of chemical and biological sensors is needed to monitor changes in ocean conditions attributable to acidification. |
