Question

1. What is the relationship between the concentration of the hydronium and hydroxide

ion and pH in any water solution?

Answer 1

- Neutral solutions: concentration of hydronium equals the concentration of hydroxide.

- Acid solutions: concentration of hydronium is greater than the concentration of hydroxide.

- Basic solutions concentration of hydronium is lower than the concentration of hydroxide.

Step-by-step explanation:

Hello,

It is widely known that the pH of water is 7, therefore the pOH of water is also 7 based on:

`pH+pOH=14`

In such a way, we can compute the concentration of hydronium and hydroxide ions as shown below:

`pH=-log([H^+])\\`

`[H^+]=10^(-pH)=10^(-7)=1x10^(-7)M`

`pOH=-log([OH^-])`

`[OH^-]=10^(-pOH)=10^(-7)=1x10^(-7)M`

Thus, we notice that the relationship between the concentration of the hydronium is equal for water or neutral solutions. Moreover, if we talk about acid solutions, pH<OH therefore the concentration of hydronium is greater than the concentration of hydroxide. On the other hand if we talk about basic solutions, pH>OH therefore the concentration of hydronium is lower than the concentration of hydroxide.

Best regards.
