Salts

Salts are non volatile solids .

• True

• False

Salt is formed by partial or

• By reaction of acid with a base

• By total replacement of ionisable oxygen atoms

• By total replacement of ionisable helium atoms

• By total replacement of ionisable hydrogen atoms

I am used as a preservative.

• Sodium Carbonate

• Sodium Bicarbonate

• Ammonium chloride

• Potassium Hydroxide

Salt can be also defined as

• Compound which dissociates in water to yield a positive ion,other than hydrogen ion

• Compound which dissociates water to yield a negative ion,other than hydroxyl ion

• Both are correct

Salts can be classified into four types based on thier

• Basicity

• Acidity

• Composition

• None of these

I am a salt formed by complete replacement of ionisable hydrogen atoms by a metallic or ammonium ion.

• Acid Salt

• Basic Salt

• Double Salt

• Normal Salt

CaCO3.MgCO3 is which type of salt.

• Common Salt

• Acid Salt

• Double Salt

• Normal Salt

I am a phenomenon in which a salt reacts with water to give a acidic or alkaline solution.

• Hydrolysis

• Effloresence

• Crystallisation

• None of these

Which of these is a example of metal + non-metal + heat is equal to salt.

• CaCO3 + 2HCl = CaCl2 + H2O + CO2

• 2Na + Cl2 = 2NaCl

• Both of these

I am a salt which is used as a pesticide.

• Copper Sulphate

• Iron Sulphate

• Mercury Chloride

• All of these
