STATEMENT -1: In the titration of `Na_(2)CO_(3)` with `HCl` using methyl orange indicator, the volume of acid required is twice that of the acid required using phenolphthalein as indicaton. STATEMENT -2: Two moles of `HCl` are required for the complete neutralisation of one mole of `Na_(2)CO_(3)`.
A
If both the statements are TRUE and STATEMENT-2 is the correct explation of STATEMENT-1
B
If both the statements are TRUE AND STATEMENT-2 is NOT the correct explanation of STATEMENT-1
The volume of CO_(2) obtained by the complete decomposition of one mole of NaHCO_(3) at STP is
The volume of CO_(2) obtained by the complete decomposition of one mole of NaHCO_(3) at STP is
Write the use of Na_(2)CO_(3) in laundries ?
The volume of 0.1 M HCl required in mL to neutralise 20 mL of a solution containing 0.106 g of Na_(2)CO_(3) is
During the titration of a mixture of Na_(2)CO_(3) and NaHCO_(3) against HCl
Solution ''X'' contains Na_(2)CO_(3) and NaHCO_(3), 20 ml of X when titrated using methyl organge indicator consumed 60 ml of 0.1M HCI solution. In another experiment, 20 ml of X solution when titrated using phenolphthalein consumed 20 ml of 0.1 M HCl solution. The concentraions ("in mol lit"^(-1)) of Na_(2)CO_(3) and NaHCO_(3) in X are respectively)
Which of these can be distinguished by adding HCl or Na_(2)CO_(3) ?
Draw the diagram that showing the reaction of Na_2CO_3 with dll. HCl and testing of evolved gas.
