A 10 mg effervescent tablet containing sodium bicarbonate and oxalic acid release 0.25 ml of CO_2 at T=298.15 K and p=1 bar. If molar volume of CO_2 is 25.0L under such condition, the number of mole of sodium bicarbonate in each tablet is 10^(-x) . What is numerical value of x. [Molar mass of NaHCO_3 =84 g mol^(-1) ]

25.3 g of sodium carbonate, Na_(2)CO_(3) is dissolved in enough water to make 250 mL of solution. If sodium carbonate dissociates completely, molar concentration of sodium ions, Na^(+) and carbonate ions, CO_(3)^(2-) are respectively (Molar mass of NaCO_(3)=106g mol^(-1) )

The amount of oxalic acid required to prepare 300 mL of 2.5 M solution is : (molar mass of oxalic acid = 90 g mol^(–1) ) :

A sample of sodium carbonate contains sodium also. 1.5 g of the sample is dissolved in water and volume raised to 250 mL. 25 mL of this solution requires 20 mL of (N)/(10)H_(2)SO_(4) solution for neutralisation. Calculate the percentage of sodium carbonate in the sample.

A 2.0 g sample of a mixture containing sodium carbonate, sodium bicarbonate and sodium sulphate is gently heated till the evolution of CO_(2) ceases. The volume of CO_(2) at 750mm Hg pressure and at 298 K is measured to be 123.9 mL . A 1.5 g of the same sample requires 150 mL of (M//10) HCl for complete neutralisation. Calculate the percentage composition of the components of the mixture.
