Q. 8 normally, the ph of the human body is fixed in a very narrow range between 7.35 and 7.45. a
patient with an acidotic blood ph of 7.3 may be treated with an alkali such as sodium bicarbonate.
why would this treatment raise the ph of the blood? can you explain it?

it is the most commonly accepted one

answer : third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol

explanation :

let us write down the given equations

equation 1 :

equation 2 :

equation 3 :

let us use hess's law to find out which 2 equations can be added to get the third equation.

let us reverse equation 2 and multiply it by 2. the new equation that we get is,

equation 4 :

let us add equation 1 & 4

the above equation is similar to equation 3 but has different value for dhrxn.

therefore third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol
