There are many methods of preparation of acids, I am listing some of them below.

1. By Direct Synthesis (reaction of elements):

Examples:

HCl (Hydorchloric acid): H2 + Cl2 => 2HCl

HBr (Hydrobromic acid): H2 + Br2 => 2HBr

These acids are also known as Hydracids, as they are prepared by the synthesis of Hydrogen with non-metal. The general equation is:

Hydrogen + Non-metal => Hydracid

2. By dissolving non-metallic oxide in water:

Examples:

H2CO3 (Carbonic acid): CO2 + H2O => H2CO3

Similarly there are many other ways of preparing acids.

Answer 2

When fossil fuel is burnt sulpher combines with oxygen to form sulpher dioxide. This reacts with oxygen and water vapor in the air and forms sulphuric acid. It may fall to the ground as acid rain.

Acid rain is a rain or any other form of precipitation that is unusually acidic, i.e. elevated levels of hydrogen ions (low pH). It can have harmful effects on plants, aquatic animals, and infrastructure through the process of wet deposition. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxides which react with the water molecules in the atmosphere to produce acids. Governments have made efforts since the 1970s to reduce the release of sulfur dioxide into the atmosphere with positive results. Nitrogen oxides can also be produced naturally by lightning strikes and sulfur dioxide is produced by volcanic eruptions.

Answer 3

soils that are derived from sandstone have low nutrients so the readily form acidic soil because of low base such as ca2+ k+ e.t.c
