question 5

Multiple Choice

Which of the following are techniques to promote particle growth?
I Use a large volume of solution so concentration of analyte and precipitant are low.

III Slowly adding precipitant with vigorous mixing as the precipitant is added to prevent a highly supersaturated condition in solution.
IV Raise the temperature of the solution to increase solubility of precipitate and decrease supersaturation.
