(a)
Interpretation:
The [H3O]+ of 0.10 M HBr should be determined.
Concept Introduction:
- pH stands for "potential of hydrogen", it is a measure of alkalinity or acidity of water-soluble substances. pH number ranges from 0 to 14.
- pH is a logarithmic scale which specify the acidity or basicity of the solution.
pOH = -log [OH]-
pH + pOH = 14
(b)
Interpretation:
The pH of the 0.10 M HBr should be determined.
Concept Introduction:
- pH stands for "potential of hydrogen", it is a measure of alkalinity or acidity of water-soluble substances. pH number ranges from 0 to 14.
- pH is a logarithmic scale which specify the acidity or basicity of the solution.
pOH = -log [OH]-
pH + pOH = 14
c.
Interpretation:
The pOH of the 0.10 M HBr should be determined.
Concept Introduction:
- pH stands for "potential of hydrogen", it is a measure of alkalinity or acidity of water-soluble substances. pH number ranges from 0 to 14.
- pH is a logarithmic scale which specify the acidity or basicity of the solution.
pOH = -log [OH]-
pH + pOH = 14
d.
Interpretation:
The balanced chemical equation for the HBr with LiOH should be determined.
Concept Introduction:
The balanced reaction is that
e.
Interpretation:
The volume of HBr solution should be determined.
Concept Introduction:
A laboratory procedure said to be titration is used in which an acid sample is neutralized with a known amount of base and by using indicator in order to determine the end-point (generally determined by color change).
Using dilution law:
