## Abstract In the present work, the effects of sulphate ions on the iron precipitation from aqueous solution were investigated. It was shown that sulphate ions delayed the iron precipitation when this ion was added in form of Na~2~SO~4~. This effect became less significant in presence of magnesium

โฆ Synopsis
A precipitation reaction between a lead-nitrate solution and oxalic acid was carried out with and without ultrasound, and the effect of ultrasonic irradiation in solution was investigated. The oxalate precipitates were a mixture of Pb oxalate and an X-phase, which seems to be a lead salt containing C2042-, NO3, and OH-It was found that irradiation with ultrasound during the precipitation reaction accelerated the formation of the X-phase.
