Question

o baza +un acod tare,3 exemple.o baza solubila+sare solubila,3exemple,va rog frumos

Answer 1

baza=NaOH(soda caustica),Ca(OH)₂ (var stins),Cu(OH)₂ (hidroxic cupric)
acid tare=H₂SO₄ (vitriol),HNO₃ (apa tare),HCl(spirt de sare)
2 NaOH+H₂SO₄=Na₂SO₄+2H₂O (stii regula baza+acid=sare+apa)
Ca(OH)₂+2HNO₃=Ca (NO₃)₂+ 2H₂O
Cu(OH)₂+H₂SO₄=CuSO₄+2H₂O

baza solubila:Ca(OH)₂,NaOH,KOH(potasa caustica)
saruri solubile:CuSO₄(piatra vanata),AgNO₃(piatra iadului),Na₂SO₄(dolamin)
ex:CuSO₄ + 2NaOH → Na₂SO₄ + Cu(OH)
