I got 9.25527 for the pKa 
<span>then for the Henderson-Hasselbalch equation: </span>
<span>9.00=9.25527+log(.600/acid) </span>
10^(-.25527)=(.600/acid)correct to this line. Then 
0.5556 = 0.6/acid and 
acid = 0.6/0.5556 = 1.08 which is the reciprocal of your number) 

<span>.5556/.600M=acid </span>
<span>acid=.925925...M </span>
<span>(.925925)*2.10L= Molarity</span>

Is the hydrogen ion concentration of a pH 3.8 solution higher or lower than that of a solution with a pH of 6.2?
vesna_86 [32]
The Hydrogen ion concentration of a pH 3.8 solution would be higher than that of a solution with a pH of 6.2. This is because since the pH scale measures the concentration of Hydrogen ions. We know that a pH range of less than 7 is considered acidic and greater than 7 is basic. If a solution is more acidic it would possess more hydrogen ions than if it weren't. In this case a pH value of 3.8 is more acidic than pH 6.2.
