20 ml of the solution containg Na_(2)CO_(3) and NaHCO_(3) is titrated

1.	20 ml of the solution containg Na_(2)CO_(3) and NaHCO_(3) is titrated with 0.1MHCI using Phenolphthalein indicator the end point was 10ml. 20ml of the same solution is titrated with 0.1M HCI, the end point was 25ml with Methylorange indicaor from the begining. NaHCO_(3)+HCl rarr NaCl +H_(2)O +CO_(2) Na_(2)CO_(3)+2HCl rarr 2NaCl +CO_(2) +H_(2)O What amount of NaOHis required to convertNaHCO_(3) to Na_(2)CO_(3) in 1 litre of solution
Answer» `2g` `20g` `1g` `0.5g` SOLUTION :`NaHCO_(3)+NaOH rarr Na_(2)CO_(3) +H_(2)O` 84g of `NaHCO_(3)` requires 40g of `NaOH` `2.1g` of `NaHCO_(3)` requires? `= (40)/(84) xx 2.1 = 1g`
