`0.1g` of a solution containing `Na_2 CO_3 and NaHCO_3` requires `10mL` of 0.01 N `HCI` for neutralization using phenolphthalein as an indicator. mass % of `Na_2 CO_3` in solution is :

Write the use of Na_(2)CO_(3) in laundries ?

The weight of 0.1 mole of Na_(2)CO_(3) is

Given two mixtures: (I) NaOH and Na_(2)CO_(3) and (II) NaHCO_(3) and Na_(2)CO_(3) . 100 ml of mixture I required w and x ml of 1 M HCl is separate titrations using phenophthalein and methyl orange indicators while 100 ml of mixture II required y and z ml of same HCl solutioni in separate titrations using the same indicators.

Calculate the molarity of 10.6% (w/v) Na_2CO_3 solution.

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)

20 mL of x M HCl neutralises 5 mL of 0.2 M Na_(2)CO_(3) solution to phenolphthalein end-point. The value of x is

Aqueous solution of Na_(2)CO_(3) is

Calculate the normally of 10.6 % (w/v) Na_2CO_3 in aqueous solutions.
