Frank is doing an experiment to find out how the amount of oxygen dissolved in water affects the growth of algae in a body of water. he dissolves different amounts of oxygen in ten otherwise identical samples of water.
what should frank do next?
a.
carefully bring each sample of water to a boil, and measure the temperature at which each boils.
b.
add equal amounts of algae to each sample of water, and measure the rates at which they grow.
c.
add a pair of minnows to each sample of water, and measure the rate at which they reproduce.
d.
place each sample of water in a freezer, and measure the temperature at which each freezes.

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
