Question

What is the nature of normal rain water?
A.Neutral
B.Acidic
C.Basic
D.None

Answer 1

Hint: Rainwater is a mixed electrolyte that comprises a variety of main and minor ions in variable concentrations. Major ingredients include sodium, potassium, magnesium, calcium, chloride, bicarbonate, and sulphate ions, as well as ammonia, nitrate, nitrite, nitrogen, and other nitrogenous molecules.

Complete answer: Neutral solution - Neutral solutions are those in which the concentrations of hydrogen and hydroxide ions are the same. A neutral solution could be a sodium chloride solution or a sugar solution. The pH of a neutral solution is 7. Another frequent material that has a pH of neutral is water. A neutral solution is one that is neither acidic nor basic.
Acidic solution - The concentration of hydrogen ions in an acidic solution (H +start superscript, plus, end superscript) is higher than in pure water. A basic solution has a concentration of H +start superscript, plus, end superscript that is lower than pure water.
Basic solution - An aqueous solution with more OH-ions than H+ions is called a basic solution. To put it another way, it's an aqueous solution with a pH above 7. Ions are present in basic solutions, which conduct electricity, turn red litmus paper blue, and are slick to the touch.
The pH of normal, clean rain is between 5.0 and 5.5, which is somewhat acidic. Rain becomes significantly more acidic when it mixes with Sulphur dioxide or nitrogen oxides, which are produced by power plants and automobiles. Acid rain typically has a pH of 4.0.
So, we conclude that the nature of normal rain water is acidic.
So, the final option (B) Acidic.

Note:
Acid rain, also known as acid deposition, is a general phrase that refers to any type of precipitation that contains acidic components, such as sulfuric or nitric acid, and falls to the ground in wet or dry form from the atmosphere. This can include acidic rain, snow, fog, hail, or even dust.
