IB DP Chemistry: HL复习笔记8.1.4 Neutralization
Neutralization A neutralisation reaction is one in which an acid (pH <7) and a base/alkali (pH >7) react together to form water (pH = 7) and a salt The proton of the acid reacts with the hydr...
IB DP Chemistry: HL复习笔记8.1.3 Characteristic Reactions of Acids
Characteristic Reactions of Acids Metals and acids The typical reaction of a metal and an acid can be summarized as acid + metal → salt + hydrogen For example: 2HCl (aq) + Zn (s) → ...

IB DP Chemistry: HL复习笔记7.1.5 Le Chatelier's Principle
Le Chatelier's Principle Position of the equilibrium The position of the equilibrium refers to the relative amounts of products and reactants in an equilibrium mixture. When the position of equilib...
IB DP Chemistry: HL复习笔记7.1.4 The Reaction Quotient
The Reaction Quotient The reaction quotient, Q, is the ratio of products and reactants for a reaction that has NOT yet reached equilibrium The expression for Q is very similar to Kc: It is a useful...
IB DP Chemistry: HL复习笔记7.1.3 Equilibrium Constant Relationships
Equilibrium Constant Relationships In the previous section we saw that the concentrations of the substances are raised to the power of the coefficients from the balanced equation This means the Kc ...
