Q. 9.4 - An Introduction to General, Organic, and Biological Chemistry

Question

Describe the formation of an aqueous $LiBr$ solution, when solid $LiBr$ dissolves in water.

Step-by-Step Solution

Answer

If ions like $KCl$ and $NaCl$ dissolved in the water, the water particles in $LiBr$ attract the ions and pull them into solution.

Step1: Introduction.

A solution is a culturally homogenous system which contains a mixture of two. A solution is typically defined as a treated water a few disintegrated contents, such as a solid or gas, but solutions containing only one solid in the other are also common, with just an alloy of silver and gold being one illustration.

Step2: Given Information.

To find the formation of an aqueous $LiBr$ solution, when solid $LiBr$dissolves in water.

Step3: Explanation.

When ionic solids such as $KCl$ and $NaCl$ dissolved in the water, the succeeding dissociation takes place:

$LiBr\left(s\right)\underset{\text{ Dissociation }}{\stackrel{{\mathrm{H}}_2\mathrm{O}}{⟶}}{\mathrm{Li}}^{+}\left(aq\right)+{\mathrm{Br}}^{-}\left(aq\right)$

The water particles are now drawing the $L{i}^{+}$ and $B{r}^{-}$ ions aside from the solid. The polar molecules in this particular instance attract and pull all ions into solution. They are hydrated as a result of all this.
