Burning fossil fuels (coal, oil and natural gas) releases carbon dioxide as well as sulphur and nitrous oxides. All these will dissolve in clouds and rain which turns the rainwater acidic (acid rain).
increasing acidity
Acid rain has a lower pH than natural rainwater, which typically has a pH around 5.6 due to dissolved carbon dioxide forming mild carbonic acid. In contrast, acid rain results from pollutants like sulfur dioxide and nitrogen oxides reacting with water vapor, leading to increased acidity (pH below 5). This higher acidity can harm ecosystems, damage buildings, and affect human health, whereas natural rainwater is generally beneficial for the environment.

to prevent acidity we must take bases such as antacid or alkaline solution as it neutralises the affect of excessive acids.
No, acidity does not directly affect the boiling point of a substance. The boiling point is mainly determined by the intermolecular forces within a substance and the external pressure exerted on it. Acidity may affect the chemical properties of a substance, but it does not have a direct impact on its boiling point.
The addition of water can affect the acidity of a highly acidic solution in one major way. This addition will bring the pH up closer to 7.
Adding sugar to soda would not directly affect the soda's acidity. The acidity of soda is primarily determined by the carbonic acid formed when carbon dioxide dissolves in water, not by the presence of sugar. However, the sweetness of the soda may mask the perception of acidity due to the added sugar.
The acidity of sugar can affect the chemical reactions in baking recipes. More acidic sugar can help baked goods rise better and have a lighter texture. However, too much acidity can also affect the taste and texture of the final product. It is important to balance the acidity of sugar in baking recipes to achieve the desired results.
The lemon's low pH balance allows it to neutralize acidity in the body by increasing the pH level when consumed, helping to balance the body's overall acidity.
