(a) when there are extra chloride ions in a solution, [CoCl4]2- complex ions can form, which are a different color than the Co2+ ions. Supposed 20% of the Co2+ ions form the complex ions when a student uses aqueous NaCl solution instead of Deionized water (he/she picked up the wrong bottom by mistake). How would the presence of [CoCl2]2- complex ions affect the % transmittance values the student reads from the spectrophotometer? Explain. (b) how are the absorbance values changed?
