Titration Calculation Flashcards
What are titrations used for?
To determine an unknown concentration of a solution
What is the unit for concentration?
Mol/Dm^3 or Mol/L
How is concentration like a ratio in how it’s measured versus actual substance concentrations
The concentration measurement is, if there were 1 dm^3 or liter of that substance, It would have X moles in that one decimeter/liter and it’d be proportionally the same as the actual substance amount and it’s concentration
What tools are used for measuring titration?
Conical flask, Burette, and pipettes (usually)
What are the usual pHs of the two substances being added together in titration
An acid and a base (Or alkali)
What is usually the formula for the equation of the reaction of two substances in titration?
Acid + Base = Salt + Water
Titre volume = ?
Start volume - End volume
What is concentration?
The amount of dissolved solute (added into solvent) per unit volume of solution (Usually dm^3 or liters)
What is a solution?
Solute dissolved in solvent (Usually something dissolved into water)
What is a first time titration that is likely to be an inaccurate result called?
Rough titration
What is more than one titration in 2 to 3 trials (w/ rough) and is usually more “accurate” than rough titrations
Accurate titrations
What are state symbols?
Symbols that tell what state of matter a substance is in (Ex. (s) for solid or (g) for gas)
What is one of the most important things to have in chemistry, labs, and chem tests?
A nice, clean looking table w/ data on it
How is a burette usually read in titration?
To the nearest half a scale, usually ending w/ 0.00 or 0.05 (Ex. 23.20 or 23.25 cm^3)
How do you actually look at a burette?
Crouch and line eyes with bottom of concave, or downward bent, water surface
