Explanation:
Which statement is true for a solution when its concentration of hydronium ions increases?
2 answers:
Answer: Its pH value decreases.
Explanation: pH is the measure of acidity or alkalinity of a solution.
pH is calculated by taking negative logarithm of hydronium ion concentration. Acids have pH ranging from 1 to 6.9 and bases have pH ranging from 7.1 to 14.
Thus as pH and are inversely related, a solution having lower pH will have more amount of
concentration. And a solution having more pH will have less amount of
concentration.
Thus when concentration of hydronium ions increases, the pH of the solution decreases and the solution becomes more acidic.

In order to deprotonate an acid, we must remove protons in order to achieve a more stable conjugate base. For this example, we can use the relationship between carboxylic acid and hydroxide.
Deprotonation is the removal of a proton from a specific type of acid in reaction to its coming into contact with a strong base. The compound formed from this reaction is known as the conjugate base of that acid. The opposite process is also possible and is when a proton is added to a special kind of base. This is a process referred to as protonation, which forms the conjugate acid of that base.
For the example we have chosen to give, the conjugate base is the carboxylate salt. This would be the compound formed by the deprotonated carboxylic acid. The base in question was strong enough to deprotonate the acid due to the greater stability offered as a conjugated base.
