acidic or basic and this is depending on what color it turns. If the unknown solution falls below 7 on the pH scale, then it is acidic but if it is more than 7 then it is basic. But if it falls straight on 7 then it is neutral. :)

What is the function of the phenanthroline solution that is added to the unknown iron solution?
phenanthroline is used as a redox indicator
What is the purpose of adding an indicator to an unknown solution?
Indicators contain chemicals that will react with certain substances. If that substance is present in your unknown solution, a reaction will occur. If no reaction occurs, then that substance is not present in your solution
What is meant by titrant in titration?
The titrant is the solution involved or used in a titration to determine the concentration of an unknown solution.
How do you determine the colorimetric estimation of unknown copper sulphate concentration in solution?
by colourimetry
What is hypothesis of a acid base titration?
to determine the concentration of the unknown solution and to determine the molar concentration of acetic acid in a sample of vinegar by titrating it with a standard solution of NaOH.
Is it advisable to use just one type of indicator to determine the nature of an unknown solution?
No; every test must be confirmed by another test.
Define standardization and state how you would go about doing it.?
Standardisation is doing a titration to work out the exact concentration of the solution you want to use to determine the concentration of an unknown solution. You must know the moles of your known solution in order to determine the number of moles for your unknown solution. You must also use your indicator to show you when it has reached it's end point.
What is the function of the phenanthroline solution that is added to the unknown iron solution?
phenanthroline is used as a redox indicator
Describe how you would measure PH of an unknown liquide?
Add universal indicator.
What is the function of the phenanthroline solution that is added to the unknown iron?
phenanthroline is used as a redox indicator

What unknown metal displaces aluminum from solution but does not displace sodium Using the activity series determine the unknown metal?
magnesium
Why is tasting or feeling an unknown solution not good way to determine whether the solution is acidic or alkaline?
This solution may be toxic, corrosive or radioactive.
What is hypothesis of a acid base titration?
to determine the concentration of the unknown solution and to determine the molar concentration of acetic acid in a sample of vinegar by titrating it with a standard solution of NaOH.
What is The process of adding a known amount of solution of known concentration to determine the concentration of another solution is called?
titration is the best method to determine the unknown concentration of the unknown. if ur known is a solid then you would have to used distilled water to ensure it is submerged before you titrate.
