| Abstract/Summary |
Precipitation of Mg(OH)2 from magnesium nitrate solution was studied by means of recording pH of the reacting mixture. Solution of NH4OH was used as the alkalizing agent. The sequence of addition of reactants, rate and time of stirring, and the excess of NH4OH with respect to stoichiometry influence change in pH, and consequently the rate of crystallization and sedimentation of the reaction product, viz. Mg(OH)2. The presence of calcium nitrate up to 10 mass % does not influence remarkably the precipitation process.
