Question

Titrations and Solution Stolchometry A istimatin is a procedure for determining the concentration of a solution by allowing to react with another solution of known concentration (called a standard solution). Acid-base reactions and oxidation-reduction reaction are used in, For example, to find the concentration of an HCI solution (an acid), a standard solution of NaOH (a base) is added to a measured volume of HCI from a calibrated color when all the acid has reacted. Using the concentration of the standard solution and the volume, we can calculate molarity of the HCI solution. A volume of 50.0ml. of 2KOH(aq)+H_2S)_ (aq) right arrow K_2SO_ (aq)+2H_2O(1) Express your answer with the appropriate units.

Explanation / Answer

V1 x N1 = V2 X N2

V1 = 15.7 ml

N1 = 1.5

V2 = 80 ml

N2 =?

N2 = 15.7 x 1.5 / 80

N2 = 0.294375 M

2. Concentration KMnO4 = 1M (pls make sure i am not able to read properly bez of poor resolution)

Volume of KMnO4 = 20.3

Weight of H2O2 = 20.3 x 1 / 1000 = 0.0203 Moles x 34.01 = 0.69 gm of H2O2
