Question

anyone have the notes of acid ,bases and salts class 10th​

Answer 1

Answer:

Arrhenius theory of acids and bases:-

Arrhenius acid – when dissolved in water, dissociates to give H+ (aq) or H3O+ ion.

Arrhenius base – when dissolved in water, dissociates to give OH− ion.

Examples:-

Acids 

• Hydrochloric acid (HCl)
• Sulphuric acid  (H2SO4)
• Nitric acid (HNO3)

Bases

• Sodium hydroxide (NaOH)
• Potassium hydroxide (KOH)
• Calcium hydroxide (Ca(OH)2)

Salts:- 

Salts are the ionic compounds which are produced after the neutralization reaction between acid and base. Salts are electrically neutral. There are number of salts but sodium chloride is the most common among them. Sodium chloride is also known as table salt or common salt. Sodium chloride is used to enhance the taste of food.

Salts having common acidic or basic radicals are said to belong to the same family.

Example:-

(i) Sodium chloride (NaCl) and Calcium chloride (CaCl2) belongs to chloride family.

(ii) Calcium chloride (CaCl2) and Calcium sulphate (CaSO4) belongs to calcium family.

(iii) Zinc chloride (ZnCl2) and Zinc sulphate (ZnSO4) belongs to the zinc family.
