Question

Which solution has the greatest number of hydroxide ions?

Answer 1

Question :-

Which solution has the greatest number of hydroxyl ions?

Answer :-

The solution that has the greatest number of hydroxyl ions is called a strong alkaline solution.

If you are given elements and you have to identify which has the greatest concentration of hydroxyl ions , then just find the element which has the highest pH value or the most basic element from the given choices.

Therefore you need to know certain names or examples of strong acids , weak acids , strong bases and weak bases .

Strong acids

Hydrochloric acid

Sulphuric acid

Weak acid

Acetic acid

Strong base

Sodium hydroxide

Potassium hydroxide

Weak base

Ammonium hydroxide

If you know all these , then you can identify that from the list the greatest number of hydroxyl ions are present in sodium hydroxide .

Hope it helps !

Answer 2

The more basic a solution is, the the concentration of hydroxide ions, OH-. A solution of baking soda, NaHCo3, with a oh of 9. The most acidic because it has the most h+ ions. I hope...... Plz mark me as brainlist
