Answer:
Percent error = - 8.1 %
Explanation:
Given data:
Actual mass = 27.20 g
Theoretical mass = 25.01 g
Percent error = ?
Solution:
Formula:
Percent error = theoretical value- actual value/ actual value × 100
Now we will put the values in formula.
Percent error = 25.01 - 27.2 / 27.2 × 100
Percent error = -2.19 / 27.2 × 100
Percent error = -0.081 × 100
Percent error = - 8.1 %

The H+ concentration that would best describe a basic solution would be the one having values less than 10^-7. The pH of a solution is related to H+ concentration by pH = -log[H+]. Therefore, as the concentration of H+ decreases the alkalinity would rise.
