After the eluting solution has risen to within two centimeters of the top of the filter paper‚ the paper was removed from the beaker‚ dried‚ and was stained with a staining reagent solution containing potassium ferrocyanide and potassium iodide. This reagent forms colored precipitates or reaction products with many cations‚ including

Audio Equalizer Research Audio Equalization Equalization‚ or EQ for short‚ means boosting or reducing (attenuating) the levels of different frequencies in a signal. The most basic type of equalization familiar to most people is the treble/bass control on home audio equipment. The treble control adjusts high frequencies‚ the bass control adjusts low frequencies. This is adequate for very rudimentary adjustments — it only provides two controls for the entire frequency spectrum‚ so each control
