a)
$C_2H_5OH + CH_3COOH \buildrel{{H_2SO_4,t^o}}\over\rightleftharpoons CH_3COOC_2H_5 + H_2O$
b)
n CH3COOC2H5 = n C2H5OH = 9,2/46 = 0,2(mol)
=> m este = 0,2.88 = 17,6 gam
c)
n este = 8,8/88 = 0,1(mol)
=> n C2H5OH = n CH3COOH = 0,1/60% = 1/6 mol
=> m C2H5OH = 46 . 1/6 = 7,67(gam) ; m CH3COOH = 60 . 1/6 = 10(gam)
a) CH3COOH + KOH -> H2O + CH3COOK
b) 2CH3COOH + CaCO3 -> H2O + (CH3COO)2Ca + CO2 \(\uparrow\)
c) 6CH3COOH + 2Al-> 3H2 + 2Al(CH3COO)3
d) 2CH3COOH + CuO -> H2O + (CH3COO)2Cu
\(a) C_6H_{12}O_6 \xrightarrow{t^o,xt} 2CO_2 + 2C_2H_5OH\\ C_2H_5OH + O_2 \xrightarrow{men\ giấm} CH_3COOH + H_2O\\ CH_3COOH + C_2H_5OH \to CH_3COOC_2H_5 + H_2O\\ b) C_{12}H_{22}O_{11} + H_2O \xrightarrow{H^+}C_6H_{12}O_6 + C_6H_{12}O_6\\ C_6H_{12}O_6 \xrightarrow{t^o,xt} 2CO_2 + 2C_2H_5OH\\C_2H_5OH + O_2 \xrightarrow{men\ giấm} CH_3COOH + H_2O\\ CH_3COOH + NaOH \to CH_3COONa + H_2O\\ c) CH_3COOC_2H_5 + NaOH \to CH_3COONa + C_2H_5OH\\ d) 2CH_3COOC_2H_5 + Ca(OH)_2 \to (CH_3COO)_2Ca + 2C_2H_5OH\)
\((CH_3COO)_2Ca + H_2SO_4 \to CaSO_4 + 2CH_3COOH\)
