Question
Answer part A,B , and C
When a compound is dissolved in water, the resulting solution is either an electrolyte or a nonelectrolyte. The solution of an electrolyte has the ability to conduct an electric current. A strong electrolyte dissociates or ionizes almost completely into ions, whereas a weak electrolyte undergoes only limited ionization or dissociation. The solution of a nonelectrolyte does not conduct a current because few, if any, ions are present in the solution. The electrical conductivity of a solution can easily be measured with a meter or a light bulb. The total ion concentration of any solution is determined by both the type and the concentration of solute. Part A The electrical conductivities of the following 0.100 M solutions were measured in an apparatus that contained a light bulb as the indicator of conductivity. Rank the solutions in order of decreasing intensity (brightest to dimmest) of the light bulb. Rank from brightest to dimmest bulb. To rank items as equivalent, overlap them. ► View Available Hint(s) Brightest Submit Al(NO3)3 KI HF CH3OH Reset Help Dimmest

When you are given a concentration for a compound, such as 1 M NaCl, it indicates the number of moles of formula units per liter (formula-unit concentration). By multiplying the formula-unit concentration by the number of ions per formula unit, you arrive at the ion concentration. For example, a 1 M solution of NaCl has a 2 M ion concentration (1 M of Nations and 1 M of Clions) because there are two ions per formula unit of NaCl. A 1 M solution of Na2S has a 3 M ion concentration (2 M of Nations and 1 M of S2- ions) because there are three ions per formula unit of Na2S. Part B What is the concentration of K+ ions in a 0.045 M K2CO3 solution assuming complete dissociation? Express the concentration in molarity. View Available Hint(s) ▼ concentration of K+ = Submit Part C —| ΑΣΦ 0.0800 M Na2CO3 0.100 M NaCl O 0.0750 M Na3PO4 0.0500 M NaOH ? M A 0.100 M solution of K₂SO4 would contain the same total ion concentration as which of the following solutions? ► View Available Hint(s)
