Answer:
9.92
Explanation:
Since we are given the concetration of H+ we can find the ph by taking the negative log and then subtracting the ph from 14 to give us pOH
-log(8.26e-5) = pH= 4.08
pOH= 14-4.08
pOH= 9.92
Answer:
Explanation:
Hello,
In this case, as the reaction between sodium hydroxide and sulfuric is:
We can notice a 2:1 molar ratio between the base and the acid, for that reason for the titration at the equivalence point we find:
Which in terms of concentrations and volumes is:
In such a way, solving for the required volume of base we find:
Best regards.
Answer:
True
