If the pH of a solution increases by 2 units (e. g., from 3 to 5), then the ratio of the new to the original hydronium ion concentration is

This question is incomplete

Explanation:

This question is incomplete. However, generally hydronium ion (H₃O⁺) is produced when hydrogen ion (usually from an acid) is attracted to the negative pole of water (which is the oxygen part).

To determine the ratio in this case is simple, the ratio of the new to the original hydronium ion concentration is;

the calculate new concentration of hydronium ion, [H₃O⁺]

pH = -log[H₃O⁺] hence,

[H₃O⁺]  = log⁻¹pH (meaning antilog of pH)

Kindly note that the pH to be used here is 2 + the original pH given

Hence, if the original pH given is 2

The new [H₃O⁺] will be 4

[H₃O⁺] = log⁻¹ 4

= 10000

Same formula should be used to determine the concentration of the original hydronium ion concentration using the original pH given.

Hence, [H₃O⁺] = log⁻¹ 2

= 100

The ratio of the new to the original hydronium ion concentration will be

10000:100

100:1

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons

a polar bond is formed when electrons are shared unevenly between atoms
