What is/are the principle ions contributing to the alkalinity of a water sample?

Answer;

The Hydroxide or Hydroxyl ions (OH)

Hydroxide ions are the principle ions contributing to the alkalinity of water sample.

Explanation;

Alkalinity refers to the measure of the buffering capacity of water. In other words this is the water's ability to resist sudden changes in pH.

pH on the other hand which is closely related to alkalinity  is a measure of how acidic or basic water is. It expresses the degree of the concentration of hydrogen ions.

Alkalinity measures the acid neutralizing capacity, as a result of ions such as hydroxide ions, carbonate  and bicarbonate ions.

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
