Question

When 0.1000mol of an unknown acid, represented by HA, are dissolved in enough water to make
1.000L of solution the resulting pH is 2.20. Calculate the value of Ka for HA.

 

Calculate the pH of a solution made from dissolving 0.100mol of acetic acid (HC2H3O2) in enough
water to make a 1.00L solution.

 

The Ka of formic acid (HCHO2) is 1.7x10-4. Calculate Kb of the formate ion, CHO2- 

 

Determine the pH of a 1.0M solution of (CH3)3NHCl. Kb =6.3x10-5 for trimethylamine, (CH3)3N.
