Question

Theorotically how many ml of 0.1 M NaOH is required to neutralise 0.05M 25 ml HCI soluiton​

Answer 1

Since 100 mL of 2 M HCl is 0.2 Moles of the HCl and 200 mL of 1 M NaOH is 0.2 Moles of the NaOH. Also, HCl is a strong acid and NaOH is a strong base, then theoretically this mixture will produce 0.2 Moles of NaCl as the HCl would react with the NaOH to produce NaCl.

NaOH+HCl→NaCl+H

2

O

0.2 0.2 0 0

0 0 0.2 0.2

If the concentrations and volumes were precise as specified. Since the salt of a strong acid and a strong base will be neutral, the solution will be pH of 7.
