Calculate the hydrogen ion concentration for a solution with the following pH value and classify the solution as acidic, basic, or neutral. a) 3.0 b) 12.0 c) 9.0

Answers: a) [H+]=1x10-3 M acid b) [H+]=1x10-12M base c) [H+]=1x10-9M base

Calculate the pH for a solution with a hydrogen ion concentration of: a) 1x10-7 b) 1x10-1 c) 1x10-13

Answers: a) pH=7 b) pH=1 c) pH=13

Example/(Calculation of pH

What is the pH of a solution with an [H+] of 1.0x10-11M? pH=-log(1.ox10-11) pH=11.00

Classify a solution as acidic, basic, or neutral from the pH and interconvert between hydrogen ion concentration and pH

pH is the negative logarithm of the hydrogen ion concentration. pH=-log[H+]

pH ranges

pH<7.00 is an acidic solution pH=7.00 is a neutral solution pH>7.00 is a basic solution

Calculation of pH

pH=-log[H+] [H+]=1x10-5M 1=when this number is exactly 1 -5=pH=5

Calculation of [H+]

pH=-log[H+] pH=6 [H+]=1x10-6M 6=when the pH=whole number 1=then this number is exactly 1 -6=the exponent=pH with a minus sign
