Answer:
- Magnesium reacts with hydrochloric acid according to the equation: Mg(s) + 2 HCl(aq) --> MgCl 2(aq) + H 2(g) This demonstration can be used to illustrate the characteristic reaction of metals with acid, a single replacement reaction, or to demonstrate the generation of hydrogen gas.
- The immediate reaction of sodium hydroxide with ferric sulphate solution gives an unstable solution containing high concentrations of the basic ions. When the ratio NaOH : Fe exceeds 0.5 : 1, a precipitate of 2Fe,O,,SO, is formed, precipitation being complete when the ratio is 2.5.: 1.
