pH Calculation Problem Set: Strong Acid and Base Only

Answer the following showing all work, equations, units, etc. Be sure to show the chemical reaction for each problem (if available).

1. What is the hydronium ion concentration and pH of a 4.25E-3M HNO3 solution?












2. What is the hydronium ion concentration and pH of a 5.25E-5M H2SO4 solution?













3. What is the hydronium ion concentration of a solution with a pH of 6.25?
















4. What is the concentration of H2SO4 in a solution with a pH of 3.25?















5. What is the pOH of a solution of 5.45E-5M calcium hydroxide solution? What is its pH?




























Answer: 1) [H+]=4.25E-3M , pH= 2.372
2) [H+]=1.05E-4M , pH= 3.979
3) [H+]=5.6E-7M
4) 2.8E-4M
5) pOH=3.962 , pH=10.038
