THE RAIN OR PRECIPITATION WHICH IS ACIDIC IN NATURE IS CALLED ACID RAIN. WET AND DRY DEPOSITIONS ARE THE TWO TYPES OF ACID RAINS.UNIVERSAL INDICATOR IS USED TO DETERMINE COLOUR CHANGE AND HOW ACIDIC AND BASIC IS THE SOLUTION.

Explanation:

The rain which is acidic in nature is called acid rain. It is a precipitated form that contains acidic components such as sulphuric acid or nitric acid. The acid rain is of two types i.)wet deposition ii.)dry deposition

Wet deposition means the acid rain will be of wet form. Dry deposition means the acid rain contains dust,gasses, rain, snow, fog and hail.

Sulphuric dioxide and nitric oxides mix with water, oxygen and other chemicals in the air and becomes sulphuric acid and nitric acids that mix with precipitation and fall on to the ground.the precipitation is said to be acidic when its ph is below 5.2.

The different polyatomic ions that form acids are H+ and SO4-2 and H+ cation and NO3- anions.

A universal indicator is a mixture of indicators which show a colour change in a solution, which interprets how acidic or basic a solution is. A universal indicator can be in paper form or present in a form of a solution.The colours from yellow to red indicate an acidic solution, colours blue to violet indicate bases and green colour indicates that a solution is neutral.

Which is a difference between molecular compounds and ionic compounds? select the correct answer below: question 5 options: molecular compounds typically form between a metal and a nonmetal, while ionic compounds typically form between nonmetals. molecular compounds result from the transfer of electrons between atoms to form ions, while ionic compounds result from the sharing of electrons between neutral atoms. molecular compounds are formed of discrete, neutral molecules, while ionic compounds are formed of large repeating arrays of opposite charges. molecular compounds have high melting points and high boiling points, while ionic
