Question

In a titration of 0.5 M HCl and an unknown concentration NaOH, 25.0 ml of NaOH was required to completely neutralize 25.0 ml of HCl. What is the concentration of the NaOH?

Answer 1

A) 25.0M

B) 1.0M

C) 0.5M

D)50.0M

Answer 2

B

Answer 3

\[HCL + NaOH \rightarrow NaCl +H20\]
Therefore, mol of HCl : NaCl
Find mol of HCl using the given information to find mol of NaCl, then concentration of NaCl.
