(a)
To determine: Whether the solubility of pyridine is more in an aqueous solution of 0.1M NaOH or 0.1M HCL.
Introduction: There are some compounds that are soluble in water and some are not. The solubilities of any weakly soluble compounds depend on pH of the solution. A particular solute can either lower or increase the solubility of another salt based on the change in pH.
(b)
To determine: The solubility of β-Naphthol more in an aqueous solution of 0.1M NaOH or 0.1M HCl.
Introduction:
There are some compounds that are soluble in water and some are not. The solubilities of any weakly soluble compounds depend on pH of the solution. A particular solute can either lower or increase the solubility of another salt based on the change in pH.
(c)
To determine: The solubility of N-Acetyltyrosine methyl ester more in an aqueous solution of 0.1M NaOH or 0.1M HCl.
