How many ions result from the dissociation of one molecule of alcl3 ?

a) 4
b)2
c)3
d) none of the above

Four ions result from the dissociation of one molecule of

Option A

Explanation:

Here, it is understood that when one-mole aluminum chloride salt dissociates than it gives one mole of aluminum ion and three moles of the chloride ion here.

This process is understood by learning the stoichiometry of chemical equations where the number of mole of reactant should be equal to the number of mole of products for any balanced chemical equation. Balanced chemical equations give quantitative data by providing a measure of elements.

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.
