Chemistry: Acids, Bases, Salts, and Equivalent Weights

A set of vocabulary flashcards defining key chemical formulas for equivalent weights and the Arrhenius concept of acids based on the provided lecture notes.

gm equivalent

$\frac{NV}{1000}$ where $N$ is Normality and $V$ is Volume.

Equivalent weight of metal

$$\frac{\text{Atomic weight}}{\text{valency}}$$

Equivalent weight of acid

$$\frac{\text{Molecular weight}}{\text{basicity}}$$

Equivalent weight of base

$$\frac{\text{Molecular weight}}{\text{acidity}}$$

Equivalent weight of Salt

$$\frac{\text{Molecular weight}}{\text{Net - change}}$$

Arrhenius Acid

Compounds which give $H^+$ ion in aqueous form.

HCl aqueous dissociation

$$HCl \rightarrow H^+ + Cl^-$$

H2SO4 aqueous dissociation

$$H_2SO_4 \rightarrow 2H^+ + SO_4^{2-}$$

CH3COOH aqueous dissociation

$$CH_3COOH \rightleftharpoons CH_3COO^- + H^+$$
