Respuesta :
Addition of a hydronium ion increases its concentration and the solution becomes more acidic, Therefore the pH decreases.
The pH value will decrease after increasing hydronium ion in concentration .
What is pH?
pH is a quantitative measure of the acidity or basicity of aqueous or other liquid solutions
What is pH scale?
pH scale is a scale used to specify the acidity or basicity of an aqueous solution. Acidic solutions (solutions with higher concentrations of H+ ions) are measured to have lower pH values than basic or alkaline solutions.
At 25 °C, solutions with a pH less than 7 are acidic, and solutions with a pH greater than 7 are basic. Solutions with a pH of 7 at this temperature are neutral (e.g. pure water). The neutral value of the pH depends on the temperature – being lower than 7 if the temperature increases above 25 °C. The pH value can be less than 0 for very concentrated strong acids, or greater than 14 for very concentrated strong bases.[3]
What is hydronium ion?
Hydronium ion chemical formula is H3O+. It can also be formed by the combination of a H+ ion with an H2O molecule.
According to question
Hydronium ion concentration is increased that means H+ ion is increased which result in make solution more acidic and having pH value lower than before.
Hence, pH value will decrease after increasing hydronium ion
