Worksheet-Organic Acids and Bases II
Worksheet – Organic Acids and Bases II Amino Acids Acids are proton donors in aqueous solutions: HA + H2O H3O + + A-acid base conjugate conjugate base acid The strength of an acid is measured by the [H3O +] at equilibrium. The higher the concentration, the stronger the acid.

Section Name Date 5.1 Acids and Bases
Acids have a pH below 7 and bases have a pH above 7. Neutral solutions have a pH of 7. On the pH scale, one unit of change represents a 10-fold change in the degree of acidity or basicity. For example, a two unit drop in pH is a 102 or 100 times increase in acidity.

Acid and Base pH Calculations Supplemental Worksheet KEY
are the concentrations of H3O+ ions, OH-ions, weak acids and weak bases. So here we have [H3O+] = n/V = 0.01 moles / 0.3 L = 0.033 M. Note we had to convert back to concentrations from moles. The volume of the solution is 0.3 L because 200 mL was added to 100 mL. Step 3: What is the pH of the solution?

Summary Sheet Year 8 Acids and Alkalis - Turton School
Summary Sheet Year 8 Acids and Alkalis: The pH Scale The pH of a solution depends on the strength of the acid: strong acids have lower pH values (pH 1-3) than weak acids. Neutral solutions have a pH of 7. For example, pure water. We can use indicators to test the pH of a substance. An indicator is a substance that
