B. GIẢI BÀI TOÁN BẰNG PHƯƠNG TRÌNH ION RÚT GỌN:
- Cần nắm bảng tan hay qui luật tan; điều kiện để phản ứng trao đổi
ion xảy ra: Sau phản ứng phải có chất không tan (kết tủa), chất điện li
yếu(H
2
O,CH
3
COOH…), chất khí.
- Khi pha trộn hỗn hợp X(nhiều dung dịch bazơ) với hỗn hợp Y(nhiều
dung dịch acid) ta chỉ cần chú ý đền ion OH
-
trong hỗn hợp X và ion H
+

trong hỗn hợp Y và phản ứng xảy ra có thể viết gọn lại thành: OH
-
+ H
+
→
H
2
O(phản ứng trung hòa)
- Ta luôn có :[ H
+
][ OH
-
] = 10
-14
và [ H
+
