Limestone (calcium carbonate CaCO 3) is a type of carbonate sedimentary rock which is the main source of the material is composed mostly of the minerals calcite and aragonite, which are different crystal forms of CaCO forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes ...

The cocoa powder was characterized in terms of solubility, wettability, fat content, pH, color properties and particle size. The protocol of Dogan et al. was used as the reference of the solubility and wettability analyses. The solubility test was performed by adding 4 g of the cocoa powder into 40 ml of water (80 °C).

Quinoline Insolubles. One of the main byproducts from carbonization is coal tar (∼812 gallons per ton of coal). It is usually refined into coal tar pitch, which is used to make chemicals, roofing and road tar, pipe enamels, and binder pitch in the manufacture of baked anodes and graphite electrodes.

CommonIon Effect. The commonion effect is a term that describes the decrease in solubility of an ionic compound when a salt that contains an ion that already exists in the chemical equilibrium is added to the mixture. This effect best be explained by Le Chatelier's if the slightly soluble ionic compound calcium sulfate, CaSO 4, is added to water.

1. Introduction During industrial production, oils such as lubricating oil and engine oil tend to age and deteriorate due to longterm contact with additives, metal powder, oil chips, and other impurities [1]. Eventually, these oils need to be replaced to avoid damage to equipment and losses in efficiency [2].

Geochemical processes and the effects of natural organic solutes on the solubility of selenium in coalmine backfill aquifers were investigated. Backfill and groundwater samples were collected at coal mines in the Powder River Basin, Wyoming. Backfill was generally dominated by aluminum (14,400 to 49,000 mg/kg (milligrams per kilogram)), iron (3,330 to 23,200 mg/kg), and potassium (7,950 to 18,00

According to Henry's law, for an ideal solution the solubility, Cg, of a gas ( × 10 −3 mol L −1, in this case) is directly proportional to the pressure, Pg, of the undissolved gas above the solution ( kPa in this case). Because both Cg and Pg are known, this relation can be rearranged and used to solve for k .

The effect is particularly well seen with lime. Minute amounts of calcium hydroxide enhance the solubility of quartz, but large amounts almost completely depress it. Lime is not very soluble in water, but it is soluble enough to give a solution which is centinormal in alkalinity and has a pH of about 12.
