What do you mean by Hydrolysis?
admin Hydrolysis is the interaction of anion or cation of the salt with water to produce an acidic or basic solution. For example: An aqueous solution of copper sulphate is acidic…
Ionic Equilibria
Derive the relationship between Kh, Kw, Ka.
Let us consider the concentration of water remains constant, the equilibrium constant for hydrolysis reaction called hydrolysis constant may be written as: Kh = / ………………………………. (1) The following equilibrium…
What do you mean by Indicators?
Indicators are the substances which indicate by change in color, the completion of the chemical reaction. We know that litmus solution is red in the acidic region and blue in…
What do you mean by titration and what do you understand by Stoichiometric point?
The titration of an acid with a base or of a base with an acid is very convenient method for measuring quantities of the substances in the solution. This process…
Define Mixed Indicators?
With ordinary acid base indicators, the color change is not sharp and abrupt, but it extends over 2 units of pH. However, sometimes, it is desirable to have sharp color…
Define Universal Indicators?
A Universal Indicator is defined as a mixture having many indicators of wide pH range. To obtain universal indicators, many indicators are mixed( though it behave as a single indicator)…
Discuss the titration of strong acid and strong base.
In acid base titration successive amounts of a base are added in acid and the pH of the solution is being noted after each addition. We then draw a titration…
Explain the titration of weak acid and a strong base?
Titration of Weak Acid and a Strong Base: For explaining titration of weak acid and a strong base let us consider an example of acetic acid i.e. CH3COOH which is…
Explain the titration of a strong acid and weak base.
Titration of Strong Acid and a Weak Base: For explaining this type of titration let us consider an example of HCl which is strong acid and ammonium hydroxide i.e. NH4OH…
Discuss the titration of weak acid and weak base?
Titration of Weak Acid and Weak Base For explaining this type of titration let us consider an example of acetic acid i.e. CH3COOH which is a weak acid and ammonium…
