Explain why {eq}NaOH {/eq} is not the best test reagent for detecting {eq}Pb^{2+} {/eq}.


Explain why {eq}NaOH {/eq} is not the best test reagent for detecting {eq}Pb^{2+} {/eq}.

Solubility Rule:

The solubility rules allow the prediction of how certain chemical compounds will react with each other or in aqueous solutions. Since some compounds easily dissolve, and others form a precipitate, these rules allow the behavior of each species to be predicted in chemical reactions. Generally, solubility can be easily predicted by the principle "like dissolves like", but these can still be affected by factors such as pressure and temperature.
