6. Acids
Acids is defined as the one which produces
hydrogen ions in water. For Example, Sulphuric
Acid, Hydrochloric Acid etc.
They give sour taste.
Acids turn blue litmus to red. This is used as
confirmation test for the presence of acid.
When acids react with metals, gases are
evolved.

7. Reactions with Acids
1. Reaction of Acid with Metal
Acid + Metal → Salt + Hydrogen gas
Mg + H2 SO4 → H2 + Mg SO4
2. Reaction of Acid with Carbonates
Na2 CO3 (s) + 2 HCl (aq) → 2NaCl (aq) + H2O(l) + CO2(g)
3. Reaction of Acid with Bicarbonates
NaHCO3 (s) + HCl (aq) → NaCl(aq) + H2O (l) + CO2 (g)
Acids
These are the substances which have
sour taste.
• They turn blue litmus solution red.
• They give H+
ions in aqueous solution.
• The term ‘acid’ has been derived
from the Latin word, acidus, which
means
sour.

BASES :
• These are the substances which are
bitter in taste and soapy in touch.
• They turn red litmus solution blue.
• They give OH−
ions in aqueous solution.

10. Reactions with Acids
1. Reaction of Acid with Metal
Acid + Metal → Salt + Hydrogen gas
Mg + H2 SO4 → H2 + Mg SO4
2. Reaction of Acid with Carbonates
Na2 CO3 (s) + 2 HCl (aq) → 2NaCl (aq) + H2O(l) + CO2(g)
3. Reaction of Acid with Bicarbonates

Strong Bases : NaOH, KOH, Ca(OH) 2
Weak Bases : NH4OH
Alkalis : These are bases which are soluble
in water [NaOH, KOH, Ca(OH) 2].
