Aliya carried out an investigation to study the type of solution formed when a solute is dissolved in a solvent. She found that three spatulas of salt produced a saturated solution when dissolved in 50 ml of water. (a) Draw the particles of the salt water produced when:
(i) one spatula of salt is added into 50 ml of water
(ii) five spatula of salt are added into 50 ml of water

(b) Does heating the water increase the rate of solubility? Give your explanation.​

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
