Acid, Base and Salts

Page 2: Chemistry acid,base,salt

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.

Page 3: Chemistry acid,base,salt

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.

Examples of acid

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.

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

Types of salts and their uses

Types of saltsSodium hydroxide.Baking soda.Washing soda.Plaster of paris.

Page 11: Chemistry acid,base,salt

Sodium hydroxide

NaCL + H2O NaOH + CL2 + H2

Page 12: Chemistry acid,base,salt

Uses

Used in processes to make products including plastics, soaps rayon and

        textiles. Removal paint. 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.

Page 13: Chemistry acid,base,salt

Baking soda

NaCL + H2O + CO2 + NH3 NH4CL + NaHCo3

Page 14: Chemistry acid,base,salt

Uses Making of cake.Ingredient in antacid.

Page 15: Chemistry acid,base,salt

Washing soda

NaCO3 Na2CO3 + H2O + CO2

Page 16: Chemistry acid,base,salt

Uses

Remove heavy stains and grease on cottons or linens by soaking in a strong solution of washing soda

Washing soda is a natural alternative to dishwashing liquids.

Washing soda is a natural alternative to dishwashing liquids.
