Form 4 Chapter 7 (Activity answer)

Activity 12

1	Standard solution – a solution in which its concentration is accurately  known
5	(a)	Calculate the mass of solute needed. Weigh out the exact mass of solute needed in a weighing bottle. Dissolved the solute in a small amount of distilled water.
	(b)	·         Wash and rinse the weighing bottle ,small beaker and filter funnel to ensure  no solute remains in any  of the apparatus used. Transfer the dissolved solute into a suitable volumetric flask.
	(c)	Add more water carefully to the volumetric flask and swirl gently. Shake well to ensure thorough mixing.
	(d)	Add water slowly by using a dropper to bring the level of the solution to the calibration mark. The volumetric flask is closed tightly and inverted several times to get a uniform or homogenous solution.

Activity 13:

3	(a)	Calculate the volume of stock solution required.
	(b)	Use a pipette to draw up the required volume of stock solution.
	(c)	Transfer the stock solution to a suitable volumetric flask.
