Question

4. What is pH? What does it measure? What are qualities of substances that are high and low in

pH? Describe the self-ionization of water.

Answer 1

Step-by-step explanation:

pH is per H+ meaning it tells you the concentration of an acid.

Measure the strength of acids (H+) and bases

Substances that have a high pH are bases- which are slippery, bitter tasting, smell good, end with a hydroxide or OH- except ammonia.

Low pH are acids. All start with H, sour tasting, normally smell bad

H20---> H+ + OH-. Self-ionization shows the hydrogen and hydroxide ions
