Instrumental Analysis for Salts (VCE SSCE Chemistry): Flashcards

Instruments measuring color intensity to determine concentration

Study of how electromagnetic radiation interacts with matter

$400$ nm to $700$ nm

Color pairs opposite on wheel; observed vs absorbed colors

$0.00$ (no absorption) to $1.00$ (complete absorption)

Graph of absorbance vs concentration using standard solutions

$x$-axis: concentration, $y$-axis: absorbance

Device splitting white light into individual wavelengths

Formed when metal ions bond to molecules/anions (ligands)

(conc. × volume of extract) / mass of dried soil
