Complexes among phosphate, carbonate and calcium have been prepared via a facile hydrothermal route. The synthesized product at the low (0.15) and the high (1.8) molar ratio of PO 4 3− /CO 3 2− is calcium phosphate hydrate and hydroxylapatite (HAp), respectively. Molar ratios of PO 4 3− /CO 3 2− are effective on the reduction of carbonate activity during the crystallization of HAp.

The solubility of calcium carbonate in water is very low, e.g., below 1 gram per litre at 20 °C under 1 atmosphere CO 2 pressure. Its solubility is strongly influenced by partial pressure of CO 2, temperature, and concentration of other salts in solution.Changes in super saturation and hence precipitation and scaling usually occur as a result of temperature increase or pressure decrease ...

Get PriceIn the aquarium hobby, ratios of calcium to magnesium of about 3:1 to 4:1 have been found to be effective. A fairly modern approach is an even lower ratio of only 2:1. Since many metal ions dissolved in the water compete to be taken up as plant nutrients, the macronutrient potassium (K) needs to be added in the calculation.

Get PriceAim: To investigate the rate of reaction between Calcium Carbonate (CaCo3) and hydrochloric acid (HCl) by changing the molarity of the acid and measuring how much Carbon Dioxide (Co2) is produced. Hypothesis: I predict that the higher the molar concentration of the acid the faster the reaction will take place therefor creating more gas in a shorter amount of time.
