In experiment 8 (part a) you will use method 2 to prepare a 50 ml buffer (buffer 2) comprising 0.5 m sodium phosphate, ph 8.0. calculate the amount in grams of nah2po4.h20 (sodium dihydrogen phosphate monohydrate, mr: 138.0); and na2hpo4 (disodium hydrogen phosphate, mr: 142.0); and select the correct answers from the dropdown boxes. calculate answer to 2 decimal places. hint: use the pka2 of 6.8 for the acid. amount (g) na2hpo4 required is amount (mass) nah2po4 required is remember to transfer the correct value to the relevant place in your lab manual as you will need this in the experiment.

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.
