Chalk dissolves in water. State whether the statement is True (or) False. And Justify it
Answers
Answer:
FALSE
Explanation:
Chalk does not dissolve in Water.
Chalk / Chalk Powder is made up of minerals / Calcium carbonate
Only a minute amount of calcium carbonate can be dissolved in the water and rest will be remain solid .
Most of the chalk will Settle down at bottom & Small part will get Suspended in water and only a minute part will get dissolved
Hence CHALK is insoluble in water
Answer:
This statement is false. Chalk does not dissolve in water.
Explanation:
Chalk is made up of calcium carbonate. Calcium carbonate has very 'low solubility' in water. So when chalks are immersed in water, a very 'small portion' of it can be dissolved but the rest portion would remain as it is. The small portion that would be dissolved would form a suspension. Therefore, chalks are insoluble and indissoluble in water.
