pka of xanthine monophosphate is 5.5. a certain experiment can detect all forms of solute molecule present in solution at greater then 10% of total solute concentration. at pH 7, the experiment will detect presence of?
To determine the presence of a solute molecule at a specific pH using the given information, we can compare the pH value to the pKa value of the solute.
In this case, we are given that the pKa of xanthine monophosphate is 5.5. The pKa value represents the pH at which half of the molecules are ionized (protonated) and half are not.
Since the pH of 7 is higher than the pKa of 5.5, we can conclude that at pH 7, xanthine monophosphate will predominantly exist in its deprotonated (ionized) form. This means that it will be detectable by the given experiment, which can detect all forms of solute molecules present in a solution at concentrations greater than 10% of the total solute concentration.
Therefore, the experiment will detect the presence of xanthine monophosphate at pH 7.
