If during the standardization of NaOH(aq), the solution was over titrated into a deep color (rather than faint), how would this affect the calculation of the concentration of NaOH?

Check the box for each statement if valid:

The calculated number of moles will be higher

The calculated number of moles will be lower

The calculated number of moles will be the same

The calculated volume of NaOH will be higher

The calculated volume of NaOH will be lower

The calculated concentration of NaOH will be higher

The calculated concentration of NaOH will be lower

Answer #1

when solution was over titrated into a deep color then more volume of titrant is required.

That indicates there are more concentrated solution of NaOH.

we know,

mole = volume of NaOH solution in L * molarity

as molarity of NaOH obtained more in compare to original molarity in NaOH solution.

so

mole of NaOH is higher than original moles of NaOH.

answer:

The calculated number of moles will be higher

The calculated concentration of NaOH will be higher

    Let’s assume that during last lab you prepared a solution of NaOH. After standardization you determined the concentration to be 0.113 M. This NaOH was then used to determine the concentration of ascorbic acid in a vitamin C tablet. To do this, a Vitamin C tablet was crushed and 0.200 g were placed in a flask with 50 mL of water. The vitamin C solution was then titrated with the standard NaOH. This was repeated twice, for a total of...

    Standardization of NaOH: Acid Base Titration Objective: In this lab, you will accurately determine the concentration of a solution of sodium hydroxide (NaOH) using a 0.500M potassium hydrogen phthalate (KHP) standard solution. Background: Acid–Base Titrations When an acid reacts with a base, a neutralization reaction occurs. The H+ ions from the acid and the HO– ions from the base combine to form water and are therefore neutralized. The other product of reaction is a salt. For example, hydrochloric acid reacts...
