Two children bring home a salt-water fish for their new fish tank. The children are eager to put their fish into the new fish ta
nk, but have to
create a salt water solution to fill the tank first. The children plan to compete to see whose solution will be finished first.
Particle Size of Salt
Temperature of Solvent
Level of Agitation
Solution A
Sea salt (small clumps)
Cold water
Slow stirring
Solution B
Granular salt (tiny grains)
Hot water
Fast stirring
What do you believe the outcome will be from these solutions?
O A Solution A will take less time to dissolve, because gently stirring will allow it to combine more evenly
OB Solution will take less time to dissolve, because hot water will cause some of the salt to evaporate.
O c Solution A will take longer to dissolve and might have some undissolved salt remaining at the bottom of the solution due to the low
temperature.
OD Solution will take longer to dissolve and might have some undissolved salt remaining at the bottom of the solution due to the
high temperature
