Lab: Stoichiometry of a Precipitation Reaction

2015-6-9  This is the lab procedure in which students produce a calcium carbonate precipitate by reacting calcium chloride with sodium carbonate. They then filter and dry the precipitate and weigh it to compare to a stoichiometric calculation. Weigh an amount of Na 2 CO 3 in excess of that which will be needed for all students (be sure to use the

Calculating chemical speciation, pH, saturation index

Unlike other commonly used calcium carbonate saturation indices (such as the Saturation Index, the Relative Saturation and the Ryznar Index), the CCPP indicates both the tendency of a water to precipitate or dissolve CaCO 3 and the quantity that may be precipitated or dissolved. In drinking water treatment, knowledge about the ability of water to deposit CaCO 3 is often used in connection with

Predicting Calcium Carbonate Scaling Process

Predicting calcium carbonate scale in water systems has been done for more than 20 years — often with questionable or even inaccurate results rather than actual field observations. Perhaps the oldest method is the marble test[1], a crude, qualitative test used primarily for potable water rather than cooling water. The marble test method led to the development of a more quantitative method by
