How many gram-equivalents of NaOH are required to neutralise 25 ~cm ³ of a decinormal HCl solution?

Options

A0.00125
B0.0025
C0.0050
D0.025

Correct answer

B. 0.0025

Step-by-step solution

For acid-base reactions, g-equivalent of acid = g-equivalent of base aligned ( HCl ) &( NaOH ) g-equivalent of acid &= (25 10⁻³ ) dm ³ 1 10 =& 25 10⁻⁴ or &=0.0025 aligned = g -equivalent of NaOH
