in demonstration of strong and weak electrolyte and non electrolytes a lightbulb apparatus that shows how much a solution conducts electricity by brightness of the light is often used. when pure water is tested the bulb does not light. when some acetic acid is added to the water the bulb burns dimly. when more acetic acid is added to the solution the bulb burns a little more brightly. if our acetic acid was used, what would be observed?
a. the bulb will not light
b. the bulb will burn brightly.
c. the bulb would burn dimly.
d. the bulb would burn out.
e. the bulb will burn more than any of the others but still not brightly.

g of sodium nitrate (NaNO,) dissolves in 100 g of water at 20°C. Is this solution saturated or unsaturated? Wha t would happen if you added ten more grams of sodium nitrate to the solution? What would if you added the ten grams and raised the temperature to 40 C? lution is unsaturated. Adding ten additional grams of solute (NaNO,) would result in a homo geneous solution. Raising the temperature of the solution by 20°C would not affect the solution...

Conductivity of Solutions For Che 2A at RCC Introduction Electrolytes are compounds which conduct electricity when dissolved in water. Strong electrolytes consist of ionic compounds which dissociate completely when dissolved in water, AND molecular compounds which completely ionize when dissolved in water. The reactions below illustrate the dissociation reaction of strong electrolytes: Na (aq) + Cl(aq) но NaCl(s) H30 CaBra(s) HO HCl(e) Ca(aq) + 2Br (aa) H*(aq) + C'(aq) Conductivity is a measure of the ability of water to pass...

It's a weak acid strong base titration
Experiment 4: Identification of an unknown acid by titration Page 2 of 15 Background In this experiment, you will use both qualitative and quantitative properties to determine an unknown acid's identity and concentration. To do this analysis, you will perform a titration of your unknown acid sample-specifically a potentiometric titration where you use a pH meter and record pH values during the titration, combined with a visual titration using a color indi- cator...
