Acid and base; solving for pH of a solution?
Determine the pH when 10.0mL of 0.300mol/L potassium carbonate combined with 15.0mL of 0.300mol/L sodium hydrogen carbonate
Thank you!!!

pH = 10.13
Explanation:
carbonate and hydrogen carbonate form a buffer solution. the cations are ininfluent. If pK_2 = 10,3 = log of second dissociation constant,
