CE ÎNSEAMNĂ LIMEWATER ÎN ENGLEZĂ?
Apa cu lamaie
Apa caldă este denumirea comună pentru o soluție saturată de hidroxid de calciu. Hidroxidul de calciu, Ca2 este slab solubil în apă Apa pură de apă caldă este limpede și incoloră, cu un miros ușor de pământ și un gust alcalin amaric de hidroxid de calciu. Termenul de var se referă la mineralul alcalin și nu are nicio legătură cu fructul acid. Apele de apă se prepară prin agitarea excesului de hidroxid de calciu în apă pură și prin filtrarea excesului de Ca2 insolubil. Atunci când excesul de hidroxid de calciu este adăugat la apa limpede, rămâne o suspensie de particule de hidroxid de calciu, oferindu-i un aspect lăptos, caz în care are denumirea comună de lapte de var. Laptele de var este o soluție alcalină cu un pH de 12,3.
