寫出下列反應(yīng)的離子方程式:
A.醋酸除去水垢的反應(yīng)CaCO3+2CH3COOH=Ca2++2CH3COO-+H2O+CO2↑CaCO3+2CH3COOH=Ca2++2CH3COO-+H2O+CO2↑
B.乙酸溶液與澄清石灰水反應(yīng)CH3COOH+OH-=H2O+CH3COO-CH3COOH+OH-=H2O+CH3COO-
C.乙酸溶液與氧化銅反應(yīng)2CH3COOH+CuO=2CH3COO-+Cu2++H2O2CH3COOH+CuO=2CH3COO-+Cu2++H2O
D.乙酸溶液與鋅粒反應(yīng)2CH3COOH+Zn=2CH3COO-+Zn2++H2↑2CH3COOH+Zn=2CH3COO-+Zn2++H2↑.
