Question

What three factors affect how fast or slow a substance will dissolve in a solution?

Answer 1

Hint: In the above question, it is asked about the factors which affect the solubility of a substance in a solution. Solubility of a substance can be defined as mixing of the substance. A substance can be soluble in one solution or not. Solubility can change with temperature and surface area of solute.

Complete step by step solution:
The three factors which affect the solubility of a solute in a solution are intrinsic solubility, temperature and the sample size of the solute.
Intrinsic solubility refers to solubility of like components, which indicates that polar solute dissolves in polar solvent and non-polar solute dissolves in non-polar solvent. Non-polar solute cannot dissolve in polar solvent and vice-versa.
Temperature: With increase in temperature, the solubility tendency of the solvent increases. If we mix sugar in water to its saturation and then if we want to add more sugar then we have to heat it.
Surface area of the solute is inversely proportional to the solubility of solute in a compound and hence, with increase in size, the substance will take time to crystallise first and then it can be soluble.

Note:
Solutions can be found almost everywhere on the earth, from the oceans to the sky. Every ocean and every lake on Earth is a solution. This is because the water is mixed with dirt, salt, and various substances to form a new substance that, though still water, isn’t healthy to drink. When rain touches the ground it mixes with dirt, rocks, and so on that it becomes a solution after coming in contact with the earth.
