Document Summary
Water molecules often split into ions of h+ hydrogen ion and oh- hydroxide ion. Acids: molecule that gives away hydrogen ions (h+ = proton: example: hcl (hydrochloric acid) splits into h+ + cl, hypoventilation: breathing too shallow, co2 levels increase. Respiratory acidosis: blood too acidic, can cause coma and death: acid test: nitric acid will dissolve many metals, but not hold. Nitric acid plus hydrochloric acid will dissolve gold, though neither can do it alone. These acids are used to determine is sample is real gold or fake: hydrofluoric acid: can cause delayed deadly reaction. Binds to free calcium ions inside body to form calcium fluoride, which prevents nervous system from getting calcium. Break molecules in cell membrane, releasing energy as heat. Salts: molecule that releases ions other than h+ when dissolved in water: example: table salt, nacl, dissolves in water to form na+ and cl- ions. It has more salts: nacl, kcl, mgcl2, cacl2.
