to indicate the changes of colour and to determine whether displacement of halogen occur
How could you make concentrated solution weaker?
A concentrated solution can be weakened by adding more of the solution material (usually water) to dilute it.
Why would adding an acid or base lower the pH in a solution?
Adding an acid to a solution will lower it's Ph, but adding a base will raise it's Ph.
