$C_2H_5OH + CH_3COOH \buildrel{{H_2SO_4,t^o}}\over\rightleftharpoons CH_3COOC_2H_5 + H_2O$

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)

Bạn có thể viết ta giấy rồi chụp lại đc không

1)

Hai phương pháp là:

1 Dùng quỳ tím: Axit axetic làm quỳ tím hóa đỏ Rượu etylic không làm quỳ tím đổi màu

2 Dùng Na₂CO₃ hoặc CaCO₃: CH₃COOH cho khí CO₂ thoát ra C₂H₅OH không có phản ứng

2)
