Ph indicator strips work by changing color in the presence of solutions with varied ph values. thinking about your procedure steps and results in part 1, why do you think the ph of the unknown weak acid was not determined with ph indicator strips until part 2?

This instrumentation is used to calculate the amount of unknown acid by measuring the amount of base it takes to neutralize the acid. To know if the solution has been neutralize there are two major ways. The first uses a pH meter in the beaker. The second uses an indicator. With this we can infer that the second method is much more detailed than the second one, that’s maybe why the pH of an unknown weak acid wasn’t determined not until the second method.

what are the two models

explanation:

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
