Beaker #3 color bwe. so the majority of cobalt is Co(H20),²"/ CoCl,² / both Co(H2O) and CoCl, 4. Describe how the color of beaker #2 changed when the first 2 mL of hydrochloric acid were added. Explain. The color went from pwai to blue because of the Hl amont nas iyher 5. Describe what happened to beaker #2 when the second 2mL of hydrochloric acid were added. Explain. 6. Describe what happened to beaker #2 when the water was added. Explain. The concentiation nas dinted by tao causting rchange in olor al back to purple. Calculations 1. What is the equation for Keg for this reaction? 1- M2V2 2. What is the concentration of cobalt (of any form) in beaker #2 initially (when 10.0mL of 0.10M CoCl2-6H20 and 5.0mL of HCI have been added together)? Hint: this is a dilution question Vi = 1OmL M1: 0.10M +5 MLof HU 2= 15.0mL Mi VI= Mz V2 Ma=?
