For each problem describe how you would prepare it in the lab (you can use a flow chart to illustrate the steps to follow once you have made your calculations. 1. to perform a laboratory practice, the following reagents are required to be prepared.
a). 250 ml of KOH solution 30% mass (25 points)
b). 250 ml of a 0.25M Fe2O3 solution (25 points)

pure water does not conduct electricity very well. however, when certain substances are dissolved in water, the solution does conduct electricity. you can make a simple device that shows how well a solution conducts electricity. this device uses a flashlight bulb to indicate how well the solution conducts electricity. the better the solution conducts electricity, the brighter the bulb will glow.
