In which beaker will an additional 10 g of sodium nitrate (NaNO3) dissolve at the slowest rate?

A. Beaker 1
B. Beaker 2
C. Beaker 3
D. Beaker 4

Answer :

If no other substance is present, the beaker with the lowest concentration of sodium nitrate will have the lowest solubility of sodium nitrate and will dissolve the additional 10 g of sodium nitrate at the slowest rate.

If we observe the temperature of the beakers, we can see that they all have the same temperature, which means the solubility will not be affected by the temperature, and all beakers can dissolve the same amount of solute at the same time.Among all the given options, the beaker that has the lowest solubility of sodium nitrate is the one that will dissolve the additional 10 g of sodium nitrate at the slowest rate.

As we know that when a solid solute dissolves in a solvent, the solute particles start separating from each other and get surrounded by the solvent particles until they are uniformly distributed throughout the solution. The speed of this process of dissolution or solubility depends on the nature of the solute and solvent, the particle size of the solute, the concentration, and other external conditions like temperature and pressure.

The solubility of sodium nitrate can be affected by the presence of other ionic compounds. For example, if any ionic compound that has a common ion with sodium nitrate is present, the solubility of sodium nitrate will decrease as it will experience a competing ion and vice versa.The answer to the given question will depend on the presence of other ions or substances that may decrease the solubility of sodium nitrate.
