0.7 g "of" Na_(2)CO_(3).xH_(2)O were dissolved in water and the volume was made to 100 mL, 20 mL of this solution required 19.8 mL "of" N//10 HCl for complete neutralization. The value of x is:

In the study of titration of NaOH and Na_(2)CO_(3) . NaOH and NaHCO_(3) , Na_(2)CO_(3) and NaHCO_(3) , phenophthalein and methyl orange are used as indicators. (a). When phenolphthalein is used as an indicator for the above mixture: (i). It indicates complete neutralisation of NaOH or KOH (ii). It indicates half neutralisation of Na_(2)CO_(3) because NaHCO_(3) is formed at the end point. (b). When methyl orange is used as an indicator for the above mixture (i). It indicates complete neutralisation of NaOH or KOH (ii). It indicates half neutralisation of Na_(2)CO_(3) because NaCl is formed at the end point. Q. A 10 g moxture of NaHCO_(3) and KOH is dissolved in water to make 1000 mL solution. 100 " mL of " this solution required 50 " mL of " 0.2 M HCl for complete neutralisation in the presence of phenolphthalein as indicator What is the percentage of NaHCO_(3) in the mixture?

A mixture containing only Na_(2) CO_(3) and K_(2) CO_(3) and weighing 1.22 g was dissolved in water to form 100 mL of solution: 20 mL of this solution required 40 mL of 0.1 N HCl for neutralisation. a. Calculate the weight of K_(2) CO_(3) in the mixture. b. If another 20 mL of the same solution is treated with excess of BaCl_(2) , what will be the weight of precipitate thus obtained? (Molarcular of Na_(2)CO_(3) = 106 , K_(2) CO_(3) = 138, BaCO_(3) = 197.4 )

1.7225 g of a metal (bivalent) salt A_(x)(CO_3)_(y)(OH)_(z) was dissolved in water to make 100 " mL of " solution 50 " mL of " this solution required 10 " mL of " 0.5 M H_2SO_4 solution for complete neutralisation using phenolphthalein indicator. Another 50 mL solution required 15 " mL of " same acid using methyl orange indicator. Deduce the formula of the salt.

4.0 g of a mixture of Nacl and Na_(2) CO_(3) was dissolved in water and volume made up to 250 mL . 25 mL of this solution required 50 mL of N//10 HCl for complete neutralisation. Calculate the percentage composition of the original mixture.
