SUMMARY

The discussion focuses on calculating the pH after adding 24 mL of 1.00 M NaOH to 25.0 mL of 1.00 M HCl. The combined volume of the solution is 49 mL, resulting in an unreacted hydrogen ion concentration of 0.02 mol/L. The final pH is calculated to be 1.69, confirming the accuracy of the solution provided by the user pavadrin.

PREREQUISITES

Homework Statement


Calculate the pH after 24 mL of 1.00 M NaOH is added from the burette to a beaker containing 25.0 mL of 1.00 M HCl


Homework Equations


pH = -log [H+]
1*10^-14 = [H+][OH-]


The Attempt at a Solution



combined volume = 49mL

n.unreacted(H+) = 0.025-0.024 = 0.001 mol

[H+] = n/V = 0.001/0.049 = 0.02 mol L-1

pH = -log[H+] = 1.69 (2 d.p)



is that correct?

many thanks,
