Question

How many moles and equivalents respectively of sodium carbonate are required to completely neutralize 1 eq of HCl?

• A. 0.5, 1
• B. 0.5, 0.5
• C. 1,1
• D. 1,0.5

Answer 1

The correct option is A 0.5, 1

1 eq of HCl is equal to 1 mol of HCl as it's n factor is 1
$N{a}_{2}C{O}_3+2HCl\to 2NaCl+H_{2}O+C{O}_2$
From the above reaction it is clear that 1 mol of HCl requires 0.5 mol and hence 1 eq of sodium carbonate
