Question

I have to make an assignment of 10 to 15 pages on acids bases and salts

Answer 1

Answer:

Hey Mate!

If u wanna make an assignment, u need to cover the whole chapter in it. That can be done when u include notes.

Notes are available on the attachment above.

I think these much notes would be beneficial for u. Rest of some substances or I can say them as combinations are available in the textbook itself for u. Like..

NaOH

CaCl2

NaHCO3

Na2CO3.10H2O

CaSO4.1/2H2O

And the water of crystallization.

They are available in textbook as notes itself, not much about them is described but that's enough for an assignment of 10 to 15 page.

Hope it helps

Answer 2

Acids

Acidity is a characteristic property of acids. Acidic substances are usually very sour. Apart from hydrochloric acid, there are many other types of acids around us. Citrus fruits like lemons and oranges contain citric and ascorbic acids while tamarind paste contains tartaric acid.

In fact, the word ‘acid’ and ‘acidity’ are derived from the Latin word ‘acidus’ which means sour. If you dip a blue litmus paper into an acid, it will turn red while a red litmus paper will not change colour. Acids also liberate dihydrogen when they react with some metals.

Bases

Bases turn red litmus paper blue while the blue litmus paper stays blue. They taste bitter and also feel soapy. Some other common examples of bases include sodium bicarbonate that is used in cooking and household bleach.

Salts

Apart from sodium chloride, other common salts are sodium nitrate, barium sulfate etc. Sodium chloride or common salt is a product of the reaction between the hydrochloric acid (acid) and sodium hydroxide (base). Solid sodium chloride is made of a cluster of positively charged sodium ions and negatively charged chloride ions held together by electrostatic forces.

Electrostatic forces between opposite charges are inversely proportional to the dielectric constant of the medium. In other words, we can say that a compound that has acidity in its nature and a compound that has basicity as its nature, may yield salts when combined together.

The universal solvent, water, has a dielectric constant of 80. Therefore, when sodium chloride is dissolved in water, the dielectric constant of water reduces the electrostatic force, allowing the ions to move freely in the solution. They are also well-separated due to hydration with water molecules.
