Rainwater is slightly acidic due to dissolved CO₂. Use the following data to calculate the pH of unpolluted rainwater at 22.6°C: vol % in air of CO₂ = 0.063 vol%; solubility of CO2 in pure water at 22.6°C and 1.09 atm is 79.29 mL CO2 per 100 mL, K₁1 of H₂CO3 = 5.27x10-7. Express the pH with 2 decimals. You might have to solve a quadratic.
A student prepares a solution for titration by adding a 10.00 mL aliquot of a solution saturated with Ca(OH)2 at 82.9°C to 25.0 mL of deionized water.
