Carlotta adds too much salt to her soup. she recalls that evaporation can be used to separate salt from salt water, so she plans to leave the soup on the stove on low heat until the soup is less salty
which will most likely happen to her soup?
a) the soup will become saltier because evaporation removes the water and leaves the salt behind
b) the procedure will make the soup less salty because the salt will evaporate and leave the pot
c) the saltiness of the soup will not change because both salt and water will evaporate
d) the heat will cause the soup to become more salty because more salt dissolves in hotter water
