Question 18

which of the following does not increase the rate of dissolving?

stirring

insulated container

temperature

surface area

I believe the answer would be insulated container.

The rate of dissolving decreases in B. Insulated container.

Solubility refers to the process at which a solvent gets completely dissolved in solution. It is a type of factor which paves way for speeding up of the mixing process. The factors such as stirring, temperature, surface area, polarity, molecular size, etc., has great influence upon the dissolving rate.  

When we stir a solution, it increases the dissolving rate of solute in solvent. Likewise when the temperature is increased, it also paves way for faster rate of dissolution. The surface area also acts as major factor for rate of dissolving because; when more area is available it leads to faster dissolving.  

Among the options given below, insulated container does not increase the rate of dissolving.

c. would be the answer : )
