IB DP Chemistry: HL复习笔记8.2.2 pH & [H⁺]
pH & [H⁺] The acidity of an aqueous solution depends on the number of H+ (H3O+) ions in solution The pH is defined as: where [H+] is the concentration of H+ in mol dm–3 The pH scale is a logari...
IB DP Chemistry: HL复习笔记8.2.1 Acid-base Titrations
Acid-Base Titrations The steps involved in performing a titration and titration calculation are outlined in Topic 1.2.9 Titrations Acid-base titrations follow the same steps and are used to find th...
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8.1.1 Brønsted–Lowry Acids & Bases
Brønsted–Lowry Acids & Bases The Brønsted-Lowry Theory defines acids and bases in terms of proton transfer between chemical compounds A Brønsted-Lowry acid is a species that gives away a proton...
IB DP Chemistry: HL复习笔记7.1.6 Catalysts & Equilibrium
Catalysts & Equilibrium Changes in concentration If all other conditions stay the same, the equilibrium constant Kc is not affected by any changes in concentration of the reactants or products ...
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...
