How Antacids Relieve Heartburn Science Project
Equation 1 says that when an acid and a base react together, they produce a salt and water Stomach acid mostly contains hydrochloric acid (HCl), a very strong acidThe active ingredient in many antacids is calcium carbonate (CaCO₃), a base that is actually found in several natural minerals, including limestone, marble, and chalkThis acid and base react as shown in A good example is the dissolution of calcium carbonate \[CaCO{3(s)} \rightleftharpoons Ca^{2+} + CO3^{2–}\] There is a slight decrease in the volume when this reaction takes place, so an increase in the pressure will shift the equilibrium to the right, with the results that calcium carbonate becomes more soluble at higher pressures112: Le Chatelier's Principle Chemistry LibreTextsTo understand the definition of a net ionic equation, recall the equation for the double replacement reaction Because this particular reaction is a precipitation reaction, states of matter can be assigned to each variable pair: A B (aq) + C Precipitation Reactions Chemistry LibreTexts3 Method for constructing EhpH diagrams The present report includes EhpH diagrams for the XHO system, where X = the symbol of an element like Na, K This is the most important system for the chemical description of elements in groundwater To understand the geochemical system of the natural barrier, we took account of notAtlas of EhpH diagrams
