Acid Base Chemistry

Water is one example of an amphiprotic compound. One result of water being amphiprotic is that a water molecule can donate a proton to another water molecule to make a hydronium ion and a hydroxide ion. This process is called the autoionization of water and occurs in any sample of water. is another way to write CO 2 (aq)]. With this buffer present, even if some stomach acid were to find its way directly into the bloodstream, the change in the pH of blood would be minimal.

But surely, if your stomach acid could dissolve the metal of a razor blade, it would dissolve itself? Surely not!

The clear lime water turns milky meaning that carbon dioxide has been produced. You may not see this for the hydrochloric acid as the reaction may happen to fast.

And your stomach is, essentially, meat, right?. At least, it is made of proteins. Well, the truth is that your stomach acid would happily digest your stomach if given a chance. And, when things don’t go right, we get things like ulcers, which are open sores or raw areas in the stomach.

How do they work? Have you ever used one of these medicines? If possible, talk to a pharmacist about these medicines and how they work. Ulcers are very painful.

What might form as a result of overproduction of stomach acid?

, which is based on the concentration of the hydronium (or hydrogen) ion in aqueous solution. A neutral (neither acidic nor basic) solution, one that has the same concentration of hydrogen and hydroxide ions, has a pH of 7. A pH below 7 means that a solution is acidic, with lower values of pH corresponding to increasingly acidic solutions. A pH greater than 7 indicates a basic solution, with higher values of pH corresponding to increasingly basic solutions.

Alumina is ampotheric hence is not a very strong base. Therefore, you can expect it to react slower. The most acid resistant ceramics are those who contain mainly silicate compounds. → 2HCl, is accompanied by evolution of heat and appears to be accelerated by moisture.

Hydrogen chloride is commonly prepared both on a laboratory and on an industrial scale by the reaction of a chloride, generally that of sodium (NaCl), with sulfuric acid (H 2 SO 4 ). It is also produced by the reaction of some chlorides (e.g., phosphorus trichloride, PCl 3 , or thionyl chloride, SOCl 2 ) with water and as a by-product of the chlorination of many organic substances (e.g., methane, benzene).

An example of an acid-base reaction that does not go to completion is the reaction of a weak acid or a weak base with water, which is both an extremely weak acid and an extremely weak base. Again, the double arrow indicates that the reaction does not go to completion but rather reaches a state of equilibrium.
