Question

Calculate the concentration (in molarity) of an NaH solution if 25.0 mL of the solution is needed to neutralize 19.7 mL of a 0.463 M HCI solution.

Answer 1

0.11 m

Step-by-step explanation:

H Ci + NaOH H2 O+ NaC1

by titration

0.0025 L of 0.13 mol Na OH = 0.00325 Mol NaOH

L

0.00325 Mol NaOH 1 Mol Hcl/I Mol NaOH = 0.00325 Mol hcl

now 0.00325 mol Hcl/ 0.030 L = 0.0108 M hcl
