Objectives UV Vis His solutions pH 4, 7, 10, 12, 14 replicate solutions using buffers make phosphate buffers for pH 4, 10, 12, 14 Preparation of buffers pH 14: 0.03433317111 g mono 0.0001690566637 g di in 50 ml water Observations Nanoparticles were formed with His for all pH ( 4, 7, 10, 12, 14) . However, only 7 and 12 seemed stable (purple solution).
