Barium chloride can be prepared from barium hydroxide or barium carbonate, the latter being found naturally as the mineral “Witherite”. These basic salts react to give hydrated barium chloride. On an industrial scale, it is prepared via a two-step process from the mineral “Baryte”: ...
Gels were prepared by mixing equal volumes of sodium-silicate solution (specific gravity l ·06) and 2·9 normal hydrochloric acid. After gelation they were C?vered with a top solution prepared by dissolving 10 g ,:nlver chloride in 50 ml. ammonium hydroxide (8.33 normal). After 10 to ...
What is the molar mass of sodium hydroxide? What is the molar mass of NaOH? What is the molar mass of methane? What is the mass of a mole of Ca(OH)2? What is molar mass and how do you get the mass? What is the molar mass of C2H6?
BaCl2helps in separating the reacted NaOH from the unreacted NaOH through the precipitation process. During titration, the HCl reacts with the unreacted NaOH so as to quantify what amount of CO2was trapped by the hydroxide because the initial volume and molarity of NaOH is there. The end point...
