No; every test must be confirmed by another test.

This solution may be toxic, corrosive or radioactive.
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.
Use a method called titration, where a known concentration of either a strong acid (to measure a weak base) or a strong base (to measure a weak acid) is slowly added to a solution of the unknown compound. By measuring the pH of the solution as you do the titration, and by measuring the volume of the known solution that you added to the unknown, you can determine the pKa of the unknown compound.For complete instructions on how a titration is performed, see the Web Links to the left of this answer.how can i determine pka value if pH is given?
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.

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
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. :)
The titrant is the solution involved or used in a titration to determine the concentration of an unknown solution.

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.

A Titration is a producers which used to determine the concentration of an acid or base.
