Why is water considered to be neutral?

Explanation:

Because it has a pH of 7, water is considered to be neutral. It is neither an acid nor a base but is the reference point for acids and bases.

Clara’s answer is essentially correct; but a little more might help to make the point. To Discuss pH, the concentration of [H+] is given in this way: pH = - log [H+]. In pure water, that concentration is 1 x 10^-7, the log of which is -7, the opposite is 7, thus the pH = 7. The [OH-] is also equal to the [H+], and is an ideal way of saying pure “water is equally as acidic as it is basic”, and is therefore neutral.

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.
