what are acids ? what are the types of acids?
Answers
Explanation:
Substances that gain H+ ions are known as acids.
Example:- Sulphuric acid, Acetic acid etc.
Types of acids :-
1) Organic Acids :- Organic are generally weak acids.
Ex:- Acetic acid
2) Inorganic Acids:- Inorganic are generally strong acids.
Ex:- Sulphuric acid
Answer:
Explanation:
Put simply, an acid is any substance that has pH of less than 7. The pH scale is used to measure how acid or alkali a substance is:
0-3 = strong acid (UI turns red)
4-6 = weak acid (UI turns orange/yellow)
7 = neutral (UI turns green)
8-10 = weak alkali (UI turns blue)
11-14 = strong alkali (UI turns purple)
The pH of an acid is determined by the concentration of Hydrogen ions (H+) the substance has when in solution. All acids contain hydrogen ions when in solution; the higher the concentration of H+ ions, the lower the pH.
Fast Fact: Bee stings are acidic. They can be neutralised using baking powder which contains sodium hydrogen carbonate - a base.
(UI = Universal Indicator - a solution that changes colour depending on the pH of a substance.)
