Acid

Produce H+ ions, LOWERS pH, increase acids

Binary Acid

H + ____ = hydro_____ic acid

Oxoacid

H____O = ____ic acid (+ate) / ____ous acid (+ite)

Oxanion

G17 (Halogens)

Per___ate (#4)

___ate (#3)

___ite (#2)

Hypo___ate (#1/

Bases

Produce OH- ions

Accepts H+ ions (more - than +), so increases pH lvls, more basic

Hydrates

Ionic + water

Name: ionic (charge l/ll/lll) ____ + mono/di/tri ___ hydrate

Mass → Mole → Particle

÷mm x av.

Mass → Mole → Particle

Mass ← Mole ← Particle

x mm ÷ av.

Mass A → Mole A → Mole B → Mass B

Mass A → Mole A → Mole B → Mass B

÷ mm A Ratio x mm B

Convert to Emperical Formula

1) assume 100 g, turn % → g

2) g/mm of atom

3) divide using the smallest no.

4) multiply if needed until it turns into a whole no. ratio

Emperical Formula → Molecular Formula

n = actual molar mass ÷ empirical formula molar mass

Molecular Formula = (Empirical Formula)n

Percent Yield

(Actual yield / Theoretical yield) x 100%

Molarity

Mole / Volume

*Must be L, not mL

*1L = 1,000 mL

Dilution

_{M1 V1 = M2 V2}

Percent Composition

[ (n x MM of elemnt) / MM of compund ] x 100%

Limit Reactant (L.R)

mol / coefficient

Limit Reactant ICF Table

To find change:

(element coefficient / L.R coefficient) x L.R Molar Mass
