about acid base and salts

1. Acid, Base and
Salts

2. Introduction
 Salts
salts are formed by the reaction take place
between acid and base.
 Acid
Acids are substance that releases H+ ions
in aqueous solution.
 Base
substance that releases OH- ion in aqueous
solution.

3. Acid
 The ability to turn blue litmus red, and the ability to
react with bases and certain metals (like calcium) to
form salts.
 A lower pH means a higher acidity, and thus a higher
concentration of positive hydrogen ion in the solution.
Chemicals or substances having the property of an acid
are said to be acidic.
 Acids are sour in taste.
 Acids are corrosive in nature.

4. Examples of acid

5. Base
 They are slippery to touch, taste bitter, change
the color of indicator red litmus paper blue, react
with acids to form salts.
 A higher PH means strong base. Value of base
starts from 8-14.
 This has concentrated of OH- ions.

6. Examples of base

7. Salt
 Salts are ionic compounds that result from the
neutralization reaction of an acid and a base.
 They are composed of related numbers of cations
(positively charged ions) and anions (negative ions) so
that the product is electrically neutral (without a net
charge).
 Some examples
acid + base salt + water
NaOH + Hcl NaCL + H2O

NaCL + H2O NaOH + CL2 + H2

12. Uses
 Used in processes to make products including plastics, soaps rayon and
textiles.

 Etching aluminum.
 Dehorning of cattle.
 During two steps of the paper making process.
 Used in relaxers to help straighten hair however this is becoming less popular
because of the possibility of chemical burns.

13. Baking soda
NaCL + H2O + CO2 + NH3 NH4CL + NaHCo3
