Standardized means that a specific amount EDTA is added to a specific volume of distilled water. Water hardness is determined by the the amount of a standard EDTA solution to change the color of the water from red to blue. For example if one added the correct amount of EDTA to twice the volume of distilled water the solution would be weak. Titration of the hard water would give a erroneous high result.
I would agree with the second one, not the first. You can't always see the chemical reaction, and it isn't always sudden. But the second claim is true.
Answer:
If a reaction takes place using all oxygen available and leaving hydrogen available, then oxygen is the limiting reactant.
Explanation:
The reaction used up all the oxygen and left over some hydrogen, so oxygen is the liting reactant.
