Která z následujících sloučenin se rozpouští ve vodě za vzniku slabě zásaditého roztoku?
Správná odpověď je: D
Slabě zásaditý vodný roztok tvoří soli silné zásady a slabé kyseliny. Hydrolýza
CH3COONa vypadá následovně:
CH3COONa + H2O → CH3COOH + Na+ +
OH−.
Hydrolýzou vzniká slabá kyselina, která zůstává v nedisociované formě, a silná zásada, která je disociovaná. V roztoku je přebytek OH− iontů, roztok je slabě zásaditý.
