Question

25 ml of 2 N HCl, 50 ml of 4 N H N O 3 and v ml of 2 M H 2 S O 4 are mixed together and the total volume is made up to 1 L after dilution 50 ml of this acid mixture completely reacted with 25 ml of a 1 N N a 2 C O 3 solution. The value of v is, 250 ml, 62.5 ml, 100 ml, 125 ml

MARKS App · Accepted Answer

aqeous solution N a 2 C O 3 is basic in nature Milli equivalents of acids = milli equivalents of N a 2 C O 3 ⇒ 2 × 25 + 4 × 50 + 4 × x × 50 1000 = 25 × 1 ∴ x = 62.5 m l
