1. What is the relationship between the concentration of the hydronium and hydroxide
Hitman42 [59]

Answer:

- 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.

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.
