What volume of 5 molar Na2So4 must be added to 25 ml of 1 molar of bacl2 to produce 10 gram of b a s o4
Kavya, the reaction occurring is as follows:-
Na2SO4+BaCl2---------> BaSO4+2NaCl
Here, 1 mol of Na2SO4 reacts with with 1 mol of BaCl2 to give 1 mol of BaSO4
Also, Molar mass of Na2SO4= 142 g/mol
Molar mass of BaSO4= 233.3 g/mol
Molar mass of BaCl2= 208.3 g/mol
Now, in BaSO4, no of moles of sulphate ion= no of moles of Barium ion
and no of moles of Barium ion in 10 g BaSO4= 10/233.3 = 0.0428
therefore, the no of moles of Sulphate ions= 0.0428
Also, the no of moles of sulphate ion here, is equal to no of moles of Na2SO4.
We know that Molarity= no of moles/volume in litres
or, no of moles= Molarity* volume of Na2SO4
Therefore, 0.0428= 5 * volume of Na2SO4
or, the volume of Na2SO4 required= 0.00856 Litres or 8.57 mL
Hope this helps you in further calculations related to this topic.

Hello Shrishti,
Hope you are doing well, the tentative dates announced on the official website has passed away, so I think it's time to visit the site regularly as the dates might be in the second week of September. Keep patience and wait for the best.
