What is the pH of the solution created by combining 12.00 mL of the 0.10 M NaOH(aq) with 8.00 mL of the 0.10 M HCl(aq)?
with 8.00 mL of the 0.10 M HC2H3O2(aq)?
i need to find the ph with HCL and then with hc2h3o2.
i got 1.30 as my anser but this was wrong i multipled all these volumes by .10 added the liters and then divided but this still is not right?
