Astudent measured the ph of four solutions. which ph indicates the highest hydronium ion concentration? 3.2 7.0 9.1 12.4

Option (a) is the correct answer.

Explanation:

It is known that pH is the negative log of concentration of hydrogen ions.

Mathematically,          pH =

For acidic solutions, pH will range fro 1 to 6.9. When a solution is neutral in nature then its pH will be equal to 7.

Lesser is the value of pH, more will be the hydrogen ion concentration present into the solution and vice-a-versa.

On the other hand, when pH will range from 7.1 to 14 then the solution will be basic in nature.

Therefore, we can conclude that a solution with pH equal to 3.2 indicates the highest hydronium ion concentration.

catya your not at all which answer i've seen you do this on another question!

here are some of the ways in which chemical and nuclear reactions differ.
