Remember the classification of bases and distribute sodium hydroxide, magnesium hydroxide, calcium hydroxide, ammonia hydrate into the appropriate groups, writing down their formulas. 1) By the number of OH-groups or 2) By the degree of dissociation 3) By solubility
1) By the number of OH-groups or acidity 1.one-acid – NaOH, NH₄OH 2.two-acid – Mg (OH) ₂, Ca (OH) ₂
2) By the degree of dissociation – 1. Weak – Mg (OH) ₂, NH₄OH 2. Strong – NaOH, Ca (OH) ₂
3) By solubility – 1.soluble or alkalis – NaOH, NH₄OH 2.insoluble – Mg (OH) ₂, Ca (OH) ₂
