Post lab Questions: 1. How would you prepare 500mL of 0.25M solution of nickel II chloride? 2. What is the resulting color of an aqueous solution of NiCl2 ? Would a 0.5M or 0.80M have greater absorbance? Explain your answer. 3. How much of 2.5M stock solution do you need to make 300mL of a 0.35M solution? How much water would you need to add to make the final volume 300mL ? 4. If a solution is red in color, what color and approximate wavelengch range would it absorb the most? 5. How would phrase the relationship between transmission and absorbance? And concentration and absorbance
