You are caring for the freshwater aquarium of a friend while they are on vacation. You are told to check the pH of the tank and make sure that it stays between 6.5 and 7.0. When you check the water the pH is 8.0. The water in the tank is:

The water in the tank is basic.

Explanation:

Acidity or basicity of an aqueous solution is determined through it pH value.

, where is concentration of (in molarity) in solution.

As a matter of fact, a pH scale has been established such as:

          Acidic (), Neutral () and Basic ()

As pH = 8.0 lies in the basic range of pH scale therefore the water in the tank is basic.

nacl is added to the aqueous of what? ? in order to get a proper answer you have to specify the exact composition of the aqueous solution.

why is arctic sea ice important? arctic sea ice keeps the polar regions cool and moderate global climate. sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. as sea ice melts in the summer, it exposes the dark ocean surface.
