Acid , Base & salt

Acid Base and Salt Introduction

What type of reaction is the following? acid + base to salt + water

Provide the following information for blue vitriol. (i)Chemical name (ii)Formula (iii) Identify whether acid, base or salt .

You are provided the solutions of sodium hydroxide (A), hydrochloric acid (B), sodium chloride ( C) and phenolphthalein (P) separately. All the solutions are colourless. How will you identify the solutions of acid, base and salt?

State on what basis are acids, bases and salts classified as strong or weak electrolytes .

Name the following A base which reacts with an acid to give a salt which on hydrolysis gives a slightly acidic solution

Assertion: The pH of a buffer solution does not change appreciably on additions of a small amount of an acid or a base. Reason: A buffer solution consists of either a weak acid and its salt with a strong base or a weak base its salt with a strong acid.

Assertion : Mixture of CH_(3)COOH and CH_(3)COONH_(4) is an example of acidic buffer. Reason : Acidic buffer contains equimolar mixture of weak acid and its salt with weak base.

In a mixture of weak acid and its salt, the ratio of concentration of salt to acid is increased ten fold. The pH of the solution

A weak acid HA has K_(a) = 10^(-6) . What would be the molar ratio of this acid and its salt with strong base so that pH of the buffer solution is 5 ?
