Below are the lab procedure on preparing standard solution from liquid. Please arrange the steps in correct order.

Question 2 options:

	Rinse the pipette three times with small volumes of distilled water and add into the volumetric pipette
	Stopper the flask and swirl to ensure that all the solution is uniformly mixed
	Calculate the volume of the concentrated solution required for the dilution
	Transfer the concentrated solution to the volumetric flask
	Use water from the dropper bottle to fill the flask exactly to the marked line of the flask
	Measure the required volume of the concentrated solution using a pipette
	Stopper the flask and invert it three times to ensure thorough mixing
	Add distilled water to the flask until the level of the solution is about 1 cm the marked line of the flask
