If the impurity is of type "n" - an element (the impurity) that has 5 electrons in its outer shell - conduction will be mainly via electrons. If the impurity is of type "p" - the atoms of the impurity has 3 electrons in its outer shell - the conduction will be mainly via holes.

Do impurities raise or lower the refractive index of a substance?
Impurities can cause a significant change in the reflective index of a liquid. Impurities totally affect the results of the experiment. It changes the reflective index and affect the concentration of the solution.
What will an indicator do in the presence of an acid or base?
This indicator changes his color.
What is the pH of boiling water?
Normal water contains impurities and minerals, so during boiling, these impurities are expelled, but this changes the pH value a little, thus the pH value would be about 7. Boiling pure water (pH7), will result in boiled pure water being at pH value 7, as there are no impurities or minerals in it
