  • What happens when limestone gets wet?

    The acid H 2 CO 3 and the CaCO 3 combine to form HCO 3 + HCO 3 + Ca. In other words, the calcite is converted to calcium bicarbonate, Ca(HCO 3) 2. This is soluble and is washed away by the rain. What happens to limestone when you treat it with dilute hydrochloric acid? Drop a small amount of dilute hydrochloric acid on your sample.Method Development for the Analysis of Aluminum, ,require dissolving and digestion of the rock samples. The next step after digestion involves the burning off of organic content, and followed by separation of the silicates from all the other elements. Once the separation is achieved, then the analysis for the elements in the samples is performed using atomic absorption spectroscopy (AAS).

  • What is the Function of Hydrochloric Acid? Education

    Jun 04, 2020· Hydrochloric acid helps your body to break down, digest, and absorb nutrients such as protein. It also eliminates bacteria and viruses in the stomach, protecting your body from infection. Hydrochloric acid contributes to protein digestion by supplying H+ which activates pepsinogen, the precursor to pepsin. Pepsinogen is secreted by chief cells in the gastric glands of the body and Chlorine in coal by ion chromatography,Sample decomposition using this multi-acid digestion technique is suited to dissolve most rock types, soils, sediments and ashed botanical samples.
