2) When 100.0 mL of a 0.50 M solution of hydrochloric acid, HCl, at 22.0°C reacts with 2.00 grams of sodium hydroxide, NaOH, the temperature increases by 12.5°C. What type of reaction (physical or chemical) takes
place? How do you know

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.
