Reaction Steps

However, when 150 mM calcium chloride solution and 75 mM tetrasodium pyrophosphate solution, both adjusted to pH 7, were used to form the initial mixture, very small fibrous calcium pyrophosphate particles with a diameter of about 1 to 3 microns were formed. Similar results were obtained when 75 mM calcium chloride solution and 37.5 mM tetrasodium pyrophosphate solution were used to form the initial mixture.
