Question

2. Using the dilution equation (Eq. 3), calculate the concentration of the three Fe) standards that will be prepared 3. What is the molar concentration of HNO3 in the extracted sample after it is diluted to 200.0 mL? (See the Procedure: Preparation of Extracted Iron) ased on equation 1 in the introduction, is iron oxidized (loss of e') or reduced (gain of e') in this experiment? Explain.(Refer to the Single Replacement Lab for more information on Redox reactions.) - 137

i need answers to all 3 of them

Answer 1

Question 2.

Here, the data (Eq. 3) is not given.

Question 3.

Here also, the data (procedure for the preparation of extracted iron) is not given. Anyhow, conceptually, when a solution is diluted, its molarity will obviously decrease because of molarity = no. of moles/volume of solution.

Question 3.

Here also the data (Eq. 1) is not given. Anyhow, conceptually higher the reduction potential of an electrode, the corresponding electrode will undergo reduction, whereas lower the reduction potential, the corresponding electrode will undergo oxidation.
