Question

The number of milli equivalent of acid in $100mL$ of $0.5NHCI$ solution is:-

• A. $50$
• B. $100$
• C. $25$
• D. $200$

Answer 1

The correct option is A $50$

The given acid is HCl, so it is monobasic (basicity = 1) because of the presence of $1H^{+}$ ion.

Now, molarity of $HCl$ = Normality of $HCl$ = 0.5 N = 0.5 M

No. of milliequivalents = $0.5\times 1000=50meq$ (Since V = 100 ml)
