The solubility of ionic solids in water differs to a great extent. Some of the ionic solids are so soluble that they are hygroscopoic in nature and absorb even water from the atmosphere. On the other hand there are substances which have o less soluble ...

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 hydroxide i.e. NH4OH which is a weak base. The reaction can be shown as: CH3COOH (aq) + ...

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 which is a weak base. The reaction can be shown as: NH4OH (aq) + HCl (aq) ---------> ...

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 a weak acid and sodium hydroxide i.e. NaOH which is a strong base. The reaction can ...

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 curve which is the plot of pH as against the amount of base which is ...

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) so that they can have a change in color over a wider pH range. Limitation ...

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 change over a narrow and selected range of pH. This can be achieved by the ...

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 of titration is done by adding a solution of the reagent of known concentration ...
