Balance the following reaction in a basic solution: Ag(s)→Ag2O(aq)
Question- A buffer is prepared by adding 30.0g of sodium acetate (CH3COONa) to 600mL of a 0.150M acetic acid (CH3COOH) solution. Determine the pH of the solution. Ka=1.8 x 10^-5
A solution contains 0.750 M HA (Ka = 1.0 x 10-6) and 0.250 M NaA. What is the pH after 0.100 mole of HCl is added to 1.00 L of this solution
