crystallization is a process which helps to separate a pure solid from a solution in its crystal form. This is the in use to purify solid. For an example the salt we get from seawater can have many impurities in it. Hence, the process of crystallization is in use to remove these impurities.
Sugar and salt are examples of products where crystallization does not only serve as separation/purification technique, but where it is also responsible for getting crystals with the right size (and shape) for further application of the products.

The answer is Single Replacement.
Chemical indicators are the chemical reagents that show the change in reaction by changing color. Chemical indicators must be chosen with a narrow pH range.
<h3>What are indicators?</h3>
Indicators are the solutions or the substances used for the qualitative and the quantitative measurement by a change in color because of the absence or the presence of the sample concentration.
The chemical indicators cannot detect the exact pH and should be used with a narrow range of pH.
Therefore, option C. the narrow range of pH is the disadvantage of chemical indicators.

These energy exchange are not change in kinetic energy. They are changes is bonding energy between the molecules. If heat is coming into a substance during a phase change, then this energy is used to by break the bounds between the molecules of the substance. The example we will use here is ice melting into water.
