Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.

13) Bromthymol blue (BTB) is a chemical indicator that is blue all alone. When combined with a basic solution, it turns green as a solution becomes more acidic it turns yellow in an acidic solution. Fill in what color you think bromthymol blue would be in each of the situations in the chart. If solution color is given, simply provide a logical, possible pH value based on the outcomes.
