Differences Between Acids and Bases

Acids and bases shows characteristics properties. Some of them are as follows:

Examples of acids: HF, HCl, HBr, HI, H2S, HNO3, HNO2, H2SO4, H2 SO3, H3PO4, H3PO3, H2 CO3

Examples of Bases: LiOH, KOH, NaOH, CsOH, RbOH and H2O.

Mg(OH)2, Ca(OH)2, Ba(OH)2, Sr(OH)2

Al(OH)3, Sn(OH)2, Pb(OH)2, Fe(OH)2, Fe(OH)3

Table : Acids and Bases are recognized by their characteristic properties, such as :

1. Acids have sour taste. For example, unripe citrus fruits or
lemon juice.2. They turn blue litmus red.3. They are corrosive in concentrated form.4. Their aqueous solutions conduct electric current.
1. Bases have bitter taste and feel slippery, for example, soap is
slippery to touch.2. They turn red litmus blue.3. They are non-corrosive except concentrated forms of NaOHand KOH.4. Their aqueous solutions conduct electric current.“
5. Smell of onion remains in an acid. 5. Smell of onion diminishes in a base.
6. Odour or smell of vanilla essence remains when it is added to an acid. 6. Odour of vanilla essence disappears when it is added to a base.
7. Colour of turmeric remains yellow. 8. Colour of turmeric turns into red from yellow.
8. Penolaphthaline remains colourless in acids. 8. Phenolaphthaline turns pink in bases.

9. Methyl Orange turns pink in acids.

10. Those compounds which provide hydrogen ion (h+) in aqueous solutions are called acids.

11. An acid is a substance which produces h+ ions in aqueous solution.

12. Acid is a species (a compound or ion) which donates or tends to donate a proton (h+).

13. An acid is a species (molecule or ion) which can accept a pair of electron. an acid is also called an electrophile (electron loving).

9. Methyle orange turns yellow in bases.

10. Those compounds, which provides hydroxyl (oh) ion in aqueous solution, are called bases.

11. A base is a substance, which gives (oh) in aqueous solution.

12. A base is a species, which accepts or tends to accept a proton.

13. A base is a species (molecule or ion) which can donate a pair of electron. an acid is also called a nucleophile (nucleus loving).
