Silver salts (eg. silver bromide) are generally kept in dark coloured bottles. 3. The residual solution remains colourless when sodium is added to cold water but turns turbid when calcium is added to the same. 4. Dilute hydrochloric acid reacts with magnesium liberating hydrogen, but the same is not liberated when the acid reacts with lead. 5.
