How might this experiment fit into the "big picture" purpose of the scientist’s research?
a. the scientist could repeat the experiment with different rock types in order to compare the effects of acid. the scientist could then make a conclusion about which building stone is best to use in an area with acid rain.
b. the scientist could repeat the experiment with a base instead of an acid in order to compare the effects on the limestone. the scientist could then make a conclusion about which building stone is best to use in an area with acid rain.
c. the scientist could repeat the experiment with blocks of limestone of different sizes in each beaker in order to compare the effects of the two different acid concentrations. the scientist could then make a conclusion about which concentration of acid has a stronger effect on the limestone.
d. the scientist could repeat the experiment with just water in all of the beakers. the scientist could then make a conclusion about which concentration of water has a stronger effect on the limestone.
