Why is a neutral solution neutral?

A neutral solution is neutral if it has the same concentration of hydrogen ions as the hydroxide ions.

Explanation:

Hydrogen ions have a positive charge [H+] while Hydroxide ions have a negative charge [OH-]. Given that a solution has equal amounts of both Hydrogen and Hydroxide ions, the charges cancel each other out resulting in a neutral solution.

answer: the figure is attached herewith.

step-by-step explanation:   we are given to sketch a unit circle and label the terminal points corresponding to

in the attached figure, we have drawn a unit circle, with centre at o(0,0) and radius 1 unit. we have labelled the points a, b, c, d and e corresponding to the angles below

∠aox = 60°,

∠box = 120°,

∠cox = 180°,

∠dox = 240°,

∠eox = 300°.

and the coordinates are a(0.5,1), b(-0.5,1), c(-1,0), d(-0.5,-1) and e(0.5,-1).

thus, the answer is complete.
