Gdevon’s laboratory is out of material to make phosphate buffer. he is considering using sulfate to make a buffer instead. the pkapka values for the two hydrogens in h2so4h2so4 are −10−10 and 2.2. will this approach work for making a buffer effective near a ph of 7? 7?

Due to operator log it is impossible to reach a pH of 7 with these pKa's or acids used.

Explanation:

Since the pKa values provided are not near to 7, reaching a neutral pH is not possible because of the governing equation equation of Buffer:

where x is\frac{HA}{A}

So the ratio of HA and A is vastly big so then it is almost impossible to arrive to this number.

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"
