Chem Ch 4 Vocab Flashcards
Mole fraction
X = Na/ Na+Nb+ Nc
Amount of a constituent divided by the total amount of all constituents in a mixture
Volume percent
= (volume of solute/ volume of solution) *100%
Strong Acids
Hydrochloric acid HCl Hydrobromic acid HBr Hydroiodic acid HI Nitric acid HNO3 Sulfuric acid H2SO4 Perchloric acid HClO4
Strong bases
Lithium hydroxide LiOH Sodium hydroxide NaOH Potassium hydroxide KOH Rubidium hydroxide RbOH Cesium hydroxide CsOH Calcium hydroxide Ca(OH)2 Strontium hydroxide Sr(OH)2 Barium hydroxide Ba(OH)2
Neutralization reaction
Acid + base -> salt+ water
Titrant
In a titration, the solution of accurately known concentration
Analyte
Substance or chemical constituent that is to be determined in an analytical procedure, like titration
Equivalence point
The point at which the reaction is complete
Indicator
Substance that changes color at or near the equivalence point called the end point
End point
When you actually stop doing the titration, usually determined by indicator color change
Molarity
M = moles of solute/ Liters of solution
M = molar mass/ liters of solution
M*V = moles
