The overall equation for the reaction between sodium carbonate solution and dilute hydrochloric acid is Na_(2)CO_(3)(aq.)+2HCl(aq.)rarrNaCl(aq)+CO_(2)(g)H_(2)O(l) If you had the two solutions of the same concentration, you would have to use double volume of HCl to reach the equivalence point. Indicators change their colours at the end point of the reaction and hence we are able to know the end points (equivalence points of reactions). How many ml of 1N HCl are requiredfor X milimoles of Na_(2)CO_(3) with methyl orange indicator

1.	The overall equation for the reaction between sodium carbonate solution and dilute hydrochloric acid is Na_(2)CO_(3)(aq.)+2HCl(aq.)rarrNaCl(aq)+CO_(2)(g)H_(2)O(l) If you had the two solutions of the same concentration, you would have to use double volume of HCl to reach the equivalence point. Indicators change their colours at the end point of the reaction and hence we are able to know the end points (equivalence points of reactions). How many ml of 1N HCl are requiredfor X milimoles of Na_(2)CO_(3) with methyl orange indicator
Answer» X ml 2 X ml 3 X ml 4 X ml Solution :In PRESENCE of MeOH indicator, velence factor of `Na_(2)CO_(3)=2` Equivalent of HCl = Equivalent of `Na_(2)CO_(3)` NV=mole `xx`V.F 1 V `=x xx10^(-3)xx2` `V=2x xx10^(-3)L=2x ml`
