On the Subject of Neutralizing Neutralization

The rules are simple.

NOTE: A# = atomic number

Acid Type

  • Hydrogen bromide
  • Hydrogen fluoride
  • Hydrogen chloride
  • Hydrogen iodide

Base Type

Condition Base Type
any NSA & batteries = 3 Ammonia
Lit CAR, FRQ, or IND Potassium hydroxide
No ports & SN has vowel Lithium hydroxide
Acid's formula has letter
in an indicator
Potassium hydroxide
D bat. > AA bat. Ammonia
Acid's A# < 20 Sodium hydroxide
None Lithium hydroxide

Acid Concentration:

  • Acid's A# - Base's A#.
  • Anion or cation's chemical symbol has vowel, - 4.
  • Anion = cation's in chemical symbol length, * 3.
  • Least significant digit of the |result| / 10
  • If 0, volume of acid / 25.

Base Concentration:

  • Titration combination is HI and KOH or HCl and NH3, 20.
  • Battery holders > port types or indicators, 5.
  • Port types > battery holders or indicators, 10.
  • Indicators > battery holders or port types, 20.
  • Either 5, 10, and 20, Closest to the cation's A#.

Drop Count:

20 / concentration of the base * volume of acid * concentration of acid

Solubility:

NH3 KOH LiOH NaOH
HBr OFF ON ON OFF
HF ON OFF ON OFF
HCl ON ON OFF ON
HI OFF OFF OFF ON
