When found in food, acids often taste ________.

When found in food, bases often taste _______.

Four solutions are tested and found to have the following pH values. Which of these substances would be considered the weakest acid?

NaOH may be found in drain cleaners and as a component of soaps. Is NaOH an acid or a base?

A substance doing the dissolving, usually the part of a solution present in the larger amount

a substance being dissolved, usually the part of the solution in the lesser amount

a substance that vigorously reacts with most metals to produce hydrogen; it readily conducts electricity; it turns litmus red and has a pH of less than 7; it typically is corrosive or sour-tasting

a substance that does not react with most metals or readily conduct electricity; it turns litmus blue and has a pH of greater than 7; it typically feels slippery and is bitter-tasting

a substance that has a pH of 7; water is an example

indicator that turns red in the presence of an acid and blue in the presence of a base

describes how much solute has been dissolved in a solution and is expressed in some kind of ratio

the measure of a solution's ability to conduct electricity

The picture shows how you might change an variable in an experiment about what affects the rate of dissolving. What results do you expect to see?

What does a neutralization reaction produce?
