when ampicillin powder is dissolved in water , the powder particles first stick together like a gum and then dissolve slowly unlike sodium chloride which dissolves unformy by fairly mixing in the solution. why is it so?
When ampicillin enters the water, its amino group -NH2 and the carboxyl group -COOH interact with water to form ionic aggregates -NH3+ and
-COO- that promote reaction between themselves (gum)...-NH3+ --OOC-...
