Examples of molar mass computations: NaCl, Ca(OH)2, K4[Fe(CN)6], CuSO4*5H2O, water, nitric acid, potassium permanganate, ethanol, fructose. Molar mass calculator also displays common compound name, Hill formula, elemental composition, mass percent composition, atomic percent compositions and allows to convert from weight to number of moles and ...
1. strong bases: Group IA metal hydroxides (LiOH, NaOH, KOH etc.) and heavier Group IIA metal hydroxides (Ca(OH) 2, Sr(OH) 2 and Ba(OH) 2) 2. solutions of strong bases have a high concentration of OHG. 3. the molecular form of the strong base does not exist in solution. B. Weak Base: dissolves but less than 100% produces hydroxides (OHG) 1 ... Trộn 100 ml dung dịch Ba(OH)2 0,5M với 100 ml dung dịch KOH 0,5M, thu được dung dịch X. Trộn 150 ml dung dịch MgCl2 0,5M với 50 ml dung dịch NaCl 1M thì nồng độ ion Cl- có trong dung dịch tạo thành là.
For example, NaH is a "very strong" base, but it reacts explosively with water. For metal hydroxide strong bases, the reaction in water is, generally, a dissociation one: SOH --> S + + OH-Where S + is the metal. This also happens for calcium hydroxide and barium hydroxide, only they go completely to Ba +2, Ca +2, and 2 OH-.
