Why is it important for all of your glassware to be clean and dry before performing a titration

Chemistry
1 answer:
ss7ja [257]3 years ago
5 0

Explanation:

It is necessary that the glassware which we use during titration needs to be clean and dry before use because otherwise the remaining reagents will get mixed up with the solutions.

As a result, this will lead to a change in analysis results.

Hence, an error will occur in the resulting values.

Also, when not cleaned properly the any other substance remaining in the glassware might react with the solution leading to a change in the solution.

In that case also, error will occur.

Solid calcium carbonate decomposes to produce solid calcium oxide and carbon dioxide gas. Express your answer as a chemical equa
Gwar [14]

Answer:

CaCO_3(s)\rightarrow CaO(s)+CO_2(g)

Explanation:

Hello!

In this case, when solid calcium carbonate, CaCO3 (s), is decomposed by the action of thermal energy (heat), solid calcium oxide, CaO (s) and carbon dioxide gas, CO2 (g) are yielded via the following reaction:

CaCO_3\rightarrow CaO+CO_2

However, since calcium carbonate is solid as well as calcium oxide and carbon dioxide is given off as a gas, we write:

CaCO_3(s)\rightarrow CaO(s)+CO_2(g)

Which also balanced.

Best regards!
