A) the Nephron's tubules are made of special cells which use receptor mediated Endocytosis to draw wastes out of the blood. They then dump the waste into the tubules along with water, this producing urine
B) special cellular filters using transport channels are used to draw wastes and water out of the blood along with large volumes of water, then much of the water is re-absorbed back into the blood leaving behind the urine
C) high pressure is used to filter wastes, nutrients, water and salts out of the blood, then the water, salts and nutrients are reabsorbed back in the blood leaving behind the urine
D) special cellular filters using transport channels are used to draw waste out of the blood which is then mixed with water as it passes through the tubules of the Nephron

Ok so this problem is driving me crazy.

If you add 2.22 g of sodium azide (NaN3 an ionic salt) to the solution of 0.734 g NH3(hydrogen azide) in 400 mL of water.
what will the new pH be? (Assume no volume change).

Please show work, so I can figure this out :) thanks!!
