✦ Synopsis

At 1.5 V applied between the electrodes on the piezoelectric crystal, many metals electrodeposit on an electrode so that the frequency changes. Iron(II1) (1 X lo-'-1 x 1O-4 M) can be determined by adsorption of iron(II1) phosphate which also causes a frequency change. Electrodeposition can be prevented by covering one electrode with a thm glass plate.
