When solutions containing 2.00 g `Na_2SO_4` and 3. 00 gm `BaCl_2` are mixed, what mass of `BaSO_4` is produced? [Formula mass `Na_2SO_4 = 142 & BaCl_2 = 208`]

Find the molarr mass of Na_(2)SO_(4) .

How will you distinguish between : Na_2SO_4 and BaSO_4

Explain why a solution of Na_2CO_3 is alkaline in nature whereas a solution of Na_2SO_4 is neutral.

0.004 M Na_2SO_4 is isotonic with 0.01 M glucose. Degree of ionisation of Na_2SO_4 is :

1 (N) H_2SO_4 solution contains how many moles H_2SO_4 :

6.2 gm of a sample containing Na_2CO_3, NaHCO_3 & non volatile impurity on gentle heating loses 5% of its weight due to the reaction 2NaHCO_3 rarr Na_2CO_3 + CO_2 + H_2O Residue is dissolved in water to form 100 ml solution & its 10 ml portion requires 7.5 ml of 0.2 M aqueous solution of BaCl_2 for complete precipitation of carbonates . What is the weight of Na_2CO_3 in gm in the origin sample ?

If equal volumes of 0.02(M) CaCl_2 and 0.0003(M) Na_2SO_4 solutions are mixed, will CaSO_4 be precipitated ? [Given : K_(sp)(CaSO_4)=2.4xx10^(-15) ]

NaOH solution is added to Al_2(SO_4)_3) solution?

Calculate the molarity and normality of a solution containing 5g Na_2CO_3 in 250 mL solution.
