As the pH of a substance rises from 7, it turns from a weak base to a strong base. A strong acid such as HCl, when mixed with water, will separate into molecules of hydrogen ions and chloride ions. That is called dissociation. Strong acids dissociate more completely than weak acids, ...
for weak base only some of its molecules are ionised. eg of strong base: NaOH ---> Na+ + OH- eg of weak base: NH3 + H2O ---> NH3+ + OH- when an acid mix/reacts with a base we don't call it's damaged people called neutralisation. Neutralisation is: the...
Classify the acid and base as either a strong acid (SA), weak acid (WA), a strong base (SB), or weak base (WB): HCl. Classify the acid and base as either a strong acid (SA), weak acid (WA), a strong base (SB), or weak base (WB): CH...
