Question

1. you add a negatively charged substance to the water molecules shown in figure 2.8 on page 28 of your textbook. how would you predict that the negatively charged substance would orient itself around the water molecules?

Explanation:

Water is a polar molecule with a slightly positive charge on the hydrogen - atoms and a slightly negative charge on the oxygen atom. Opposite charges attract. So, a negatively - charged substance will be attracted to the slightly positive hydrogen atoms of the water molecules.

Answer:

The negatively charged substance would orient itself such that it is attracted to the slightly positive hydrogen atoms of the water molecules.
