Calculating pH and pOH 1. What is the poH of a 0.36 M solution of sodium hydroxide
(NaOH)?

2. Calculate the pH of a sodium hydroxide solution with a
pOH of 4.6

3. What is the pH of a substance that has a hydrogen ion
concentration of 6.9x10^-2 M?

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
