Relationship between ph scale and hydronium ions

The pH scale is a method to measure if a substance is an acid or base. The amount of hydronium and hydroxide ions there are in a solution determines how acidic or basic it is. Water is the most neutral on this scale, with an equal number of hydronium and hydroxide ions.

When a substance has more hydronium ions, it is more acidic.

When a substance has more hydroxide ions, it is more basic.

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .

e

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.
