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.

Fact: The pH indicator Alizarin Yellow has a pH range of 10.0 (yellow) to 12.0 (red). Question: You added 8 drops of Alizarin Yellow indicator to 50 mL of distilled water and your solution appears yellow and transparent. What colour would your solution change to if you added 20 drops of 2.0 M NAOH? Think about what you did in the lab. Remember the results are reported on going from acid to base. O Your solution would turn red in colour and would be transparent (see through). O None of these answers are correct. Your solution would become colourless. OYour solution would remain yellow in colour and would be transparent (see through). Your solution would turn orange in colour and would be transparent (see through).
