Question

Estimation of barium as barium sulphate by gravimetric method

Answer 1

the sun and moon gravitional forcre is due to the copper sulphate and mass is so light and hard to touch

Answer 2

Answer:

To estimate the quantity of barium in the entirety of the given solution of barium chloride.

Explanation:

Sulphate exists precipitated as barium sulphate in the hydrochloric acid medium by the addition of barium chloride solution. The reaction exists taken out about the boiling temperature. The precipitate exists filtered and washed to extract the chlorides, then dried or ignited and weighed as $BaSO_{4}$.

The Gravimetric Estimation of Barium:

The given barium chloride solution exists made up of a definite volume. A measured volume of it exists then treated with dilute sulphuric acid and barium precipitated as barium sulphate.

$\mathrm{BaCl}_{2}+\mathrm{H}_{2} \mathrm{SO}_{4} \rightarrow \mathrm{BaSO}_{4}+2 \mathrm{HCl}$

The precipitated barium sulphate exists split and weighed. The mass of Barium in the total of the given solution exists calculate at 233.36 g of barium sulphate has 137.36 g of barium.
