MES is a buffering agent commonly used in biology and biochemistry. It has a pKa of 6.15. Its acid form has a molar mass of 195.2 g/mol and its sodium salt (basic form) has a molar mass of 217.22 g/mol. What is the pH of a 0.10 M solution of MES that is an equimolar solution of MES and its conjugate base?

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.
