Today Ray and I worked on making ferrofluid again. Since we did not have ferric chloride we had to substitute it with 40 ml of the green ferrous chloride. We added the 40 ml of the green ferrous chloride to the brown ferrous chloride mixture. Then we added 400 ml of ammonia to the ferrous chloride mixture. The color of this new mixture of Ferric Chloride and Ammonia is now a dark brown. Tomorrow, we are going to heat the mixture for an hour and ass oleic acid.
