What are some precautions that should be observed when collecting samples for DO determination, to ensure the amount of oxygen in the sample is representative of the DO at the site. If iodide is combined with lead, it is insoluble. Evidence of a chemical reaction? Sodium chloride, a common salt, dissolves in water due to the attraction between the negative part of the water (oxygen) and the positive part of the salt (sodium). Its like a teacher waved a magic wand and did the work for me. The reason is that freezing point occurs when the vapor pressure of the liquid and solid solvent are at equilibrium. There are other easy ways to express the concentration of a chemical solution. Table salt is made from a combination of atoms of sodium (Na) and chlorine (Cl) in a ratio of 1:1 forming the compound NaCl. Molality is used to express the concentration of a solution when you are performing experiments that involve temperature changes or are working with colligative properties. When salt is mixed with water, the salt dissolves because the covalent bonds of water are stronger than the ionic bonds in the salt molecules. There is a reaction between the sodium carbonate and the HCl that gives off a gas with the result that there is some HCl left over - the resultant solution is acidic in nature. This is clearly going to be soluble and won't precipitate. Compare and contrast humidity and relative humidity.
