Question

25ml of the given HCl solution requires 30mL of 0.1M
sodium carbonate solution. What is the volume of
this HCl solution required to titrate 30 mL of 0.2 M
aqueous NaOH solutions​

Answer 1

Answer:

for me it is too hard to be understood

Answer 2

HCL with Na2Co3

Eq. Of HCl =eq. Of Na2Co3

25/1000 into M into 1 =30/1000 into 0.1 into 2

M = 6/25 M


Eq of HCL = eq of Na2Co3


6/25 into 1 into v/1000=30/1000 into 0.2 into 1


V=25ml
