Question

to identify the law of conservation of mass a student added 10mL of 5 %barium chloride solution into 10mLof5% sodium sulphate solution. which one of the following is the correct observation (a) a clear solution is obtained (b) the solution terns to red colour (c) a yellow precipitate is formed. (d) a white precipitate is formed​

Answer 1

Answer:

a white precipitate is formed

Explanation:

when BaCl2 reacts with Na2SO4 then NaCl Nd BaSO4 are formed and the BaSO4 formed is white in colour and is ppt in nature

Answer 2

When 10mL of 5 barium chloride answer into 10mLof5% sodium sulphate answer a white precipitate is formed:

Explanation:

• In this response a white colored precipitate of Barium Sulphate is formed and additionally the alternative product formed is sodium chloride.
• This response can both be known as a precipitation reaction or Double displacement reaction however the latter can be greater convenient while describing this kind of reaction.

• mass of BaCl2 + Na2SO4 = mass of BaSO4 + NaCl
