2Y: Acids and Bases Flashcards
What are the 2 most common laboratory acids?
The two most common laboratory acids are hydrochloric acid (HCl)
and sulfuric acid (H2SO4). Sulfuric acid and hydrochloric acid are strong acids.
What are the 2 most common bases?
The most common bases that are used in the school laboratory are sodium hydroxide and calcium hydroxide.
- The chemical formula for sodium hydroxide is NaOH. Sodium hydroxide is commonly called caustic soda.
- Lime water is a chemical that is used to test for carbon dioxide. Lime water contains a base called calcium hydroxide. The formula for calcium hydroxide is Ca(OH)2
What is neutralisation reaction?
The reaction between an acid and a base is called a neutralisation reaction. The substance formed in a neutralisation reaction is often neutral (that is, neither acidic nor basic).
Brushing your teeth with toothpaste is an example of a neutralisation reaction.
Toothpaste is a basic substance. It neutralises the acids that damage your teeth.
When an acid and a base neutralise each other, a salt and water are formed.
acid + base = salt + water
The most common example of a neutralisation reaction is the reaction between
hydrochloric acid and sodium hydroxide.
HCl + NaOH = NaCl + H2O
hydrochloric acid + sodium hydroxide = sodium chloride + water
What is Acid Rain?
Acid rain is a mixture of sulfuric and nitric acids dissolved in water.
What are the impacts of Acid Rain?
Acid rain destroys lakes, kills fish, harms trees and attacks stone.
