The term Standardized means that the concentration has been guaranteed through chemical tests. That's it, period. If I titrate a solution and get an answer, it is standardized... that's it. This is why we titrate the sodium hydroxide solution before we use it to titrate an acid solution. We standardize the sodium hydroxide before we use it to gauge the acid concentration.
Standardized = measured the concentration... and guarantee it's accuracy.

Standardize Meaning

A standardized solution is one that has had the concentration empirically determined through the use of an analytical test (essentially what chem_man said). For instance, if you make up a 0.1 M sulfuric acid solution and titrate it with an accurately made and characterized NaOH solution, you might find out that the actual molarity is 0.10012 M. This does not seem like much, but it can be very important if the sulfuric acid solution is going to be used in a quantitative test and highly accurate results are required.

A standardized solution doesn't mean 1 molar like dude #1 said! It just means that you know the exact concentration of the solution. A one molar solution means that there is exactly 1 mole (6.022X10^23) molecules of solute dissolved into 1 liter total volume of solution. Well, not exactly that number, but to as many significant figures as you have. Eg. NaCl MW= 58.45 g/mol. To get a 1.00 molar solution, you would start with 58.45 grams of NaCl and dilute to a total volume of 1.00 liters of water.

a standard solution is of known weight and concentration. This means that calculations can be accurately derived from this solution. It however doesn't mean that its specifically one mole but it can be.

a 3 molar solution indicates 3M. 3M=3 mol/L stoichiometry would read 3Zn + 2H3PO4 ---> Zn3(PO4)2 + 3H2 17.5g/65.38g Zn=.267 mol Zn 3mol Zn: 2mol H3PO4 1mol Zn: 2/3mol H3PO4 where x=no. L .267mol*2/3=3mol/L*x L .178mol=3mol*x .178mol/3mol=x .0593=x so you need 59.3 mL or .0593 L to have the reaction move to completion.

A standard solution is 1 molar. To standardize something means to make them all the same. Like mixing up a large batch at some molarity and using it in each subset of the experiment.

This refers to everything within the solution being one mole.

It means it has been analyzed and the concentration is specified.
