What you mean by FSP

One defintion is Foreign Service Pension.

What is meant by ionic product of water

H2O=H+ +OH-

Ka=[H+][OH-]/[H2O]

Ka[H2O]=[H+][OH-] [H2O]=Constant

Ka=[H+][OH-]=Kw=1*10-14

What is the relationship between pH and pOH

pH + pOH = 14

What kind of fraction has a value less than 1

1/2 is less than one.

What does the rate law use to determine the rate of a reaction

The rate of a reaction is calculated using the concentrations of reactants.

What property is used to calculate the pH of a solution
