Solution A could have this dissolved in it A sugar Solution B could have this dissolved in it concentrated A solution like solution A that can conduct electricity electrolyte salt, acid, or base2 2 points SP56.a How could you increase the conductivity of a solution? O Increase the temperature of the solution. O Decrease the concentration of ions in the solution. O Use a weaker acid or base to make the solution. O Increase the concentration of ions in the solution. 3 2 points SP56.a Sugar is added to tea to make sweet tea.

How can he speed up the rate of dissolution of the sugar? Choose ALL three correct answers. Break up the sugar so the particle size is smaller. Agitate the lemonade solution. Add additional solute. O Increase the temperature of the lemonade. Then add ice to cool it back down so it doesn't taste bad.5 2 points SPS6.b How quickly will a mint dissolve? Solute Average Time to dissolve (seconds) mint cut in half, not swirled 140 mint cut in half, swirled 70 whole mint, not swirled 200 whole mint, swirled ? mint cut into small pieces, not swirled 50 Students were asked to place a mint in their mouths and determine how long it took for the mint to dissolve. The condition of the mint varied in each student group. One group of students was asked to leave a whole mint in their mouth, not moving it around, and let it dissolve. Another group swirled a whole mint around in their mouths, while the other groups used mints broken into smaller pieces. See the chart for all of the manipulated variables. After reviewing that data table, what kind of result would you predict for the swirled, whole mint? O between 160 and 220 seconds between 80 and 100 seconds between 40 and 60 seconds O between 20 and 30 secondsKCl is used to test the factors that atfectthe rate of dissolution.
