Acid base balance in the human body is essential for all living organisms. pH stands for potential hydrogen, and is defined as the Negative logarithm of the concentration of hydrogen ions. pH is measured on a scale ranging from 0 to 14. 0 is considered highly acidic, while a pH of 14 is very basic, and a pH of 7 is neutral.

Acids and bases can neutralise each other. A base that can dissolve in water is also called an alkali.Acid and Bases Homework Help - K-12 Grade Level, College Level Chemistry. Introduction to Acid. An acid is a substance which reacts to a base. Generally, acids can be recognized as tasting sour, reacting with metals for example- calcium and bases for example- sodium carbonate. Aqueous acids have pH below 7, as the acidity increases, pH decreases. Chemicals having characteristics of an acid are.

In this section we will be talking about the basics of acids and bases and how acid-base chemistry is related to chemical equilibrium. We will cover acid and base definitions, pH, acid-base equilibria, acid-base properties of salts, and the pH of salt solutions. Our mission is to provide a free, world-class education to anyone, anywhere. Khan Academy is a 501(c)(3) nonprofit organization.
This Acid and Base Homework Worksheet is suitable for 9th - 12th Grade. In this acid and base instructional activity, students answer 7 questions about acidic and basic solutions such as the color each turns litmus paper, the pH values, the balanced equations for neutralization reactions and their pH and concentrations.
Acid-base equilibria. The module of the A level course on acid-base equilibria extends and applies ideas learned earlier in the course regarding equilibrium constants, and topics in this section are exclusively second year A level material. Much of the section focuses on the concept of pH. Students must develop an intimate understanding of pH in terms of its rigorous definition as -log 10 (H 3.
