mention two differences between acid and base. What colour changes occur in litmus in acid and base. Name a synthetic indicator of acid and bases. give one example of neutralisation from daily life.
Answers
Answer:
As we know that acid is a compound which when dissolved in water gives H+ ion. Whereas, base is any substance which donates electrons, and accepts electrons and releases OH− ions.
Complete Solution :
Let's discuss about the main differences in between acids and bases:
ACIDS BASES
Acid are those that can donate electrons Bases are those that can accept protons
The pH values of acids are basically less than 7 The pH values of bases are basically more than 7.
Acids turn blue litmus red. The Base turns red litmus blue.
Acids remain colourless when dissolved in phenolphthalein Bases makes solution pink coloured when dissolved in phenolphthalein
When these are dissolved in water then releases H+ ions. When these are dissolved in water then releases OH− ions.
Examples: Acetic acid, sulphuric acid Examples: NaOH, Ammonia
- Neutralization reaction is the reaction between an acid and a base.
In this reaction water and salt is formed as products. This reaction is called a neutralization reaction because the acid and base neutralize each other to form water and salt. We can see the example of neutralization reaction:
HCl+NaOH→NaCl+H2OH2SO4+NaOH→Na(SO4)2+H2O
