Potassium Chromate K2CrO

Calculate the percent composition of potassium chromate, K2CrO. ... 

The precipitation reaction that occurs when yellow potassium chromate, K2CrO aq), is mixed with a colorless barium nitrate solution, Ba(N03)2(aq)... 

The permeability of frozen ground barriers was directly measured in a recent laboratory project for the US Department of Energy. The soils were uncontaminated samples from DoE nuclear reservations a coarse silty sand from Hanford, Washington, and a clay soil from Oak Ridge, Tennessee. The test fluids were dilute aqueous solutions of potassium chromate K2CrO ) trichloroethylene (TCE) and radioactive cesium ( CsC/2), concentrated CaC/2 brine, and pure decane. The choice of soils and chemicals provided a sampling of the characteristics of liquid contaminants at many of the DoE s leaking nuclear waste sites.
