Good Antiseptic For Small Cuts And Grazes


Recommended Posts


for small cuts and grazes i give a good wash when the wound is fresh then leave the dog to clean it if it can reach.

 

 

The solution is 9 grams of sodium chloride (NaCl) dissolved on water, to a total volume of 1000 ml. As 1 grams NaCl occupies 0.18 level teaspoons, 9 grams NaCl is 1.62 level teaspoons. The mass of 1 millilitre of normal saline is 1.0046 gram at 22 °C.[2][3] The molecular weight of sodium chloride is approximately 58.5 grams per mole, so 58.5 grams of sodium chloride equals 1 mole. Since normal saline contains 9 grams of NaCl, the concentration is 9 grams per liter divided by 58.5 grams per mole, or 0.154 mole per liter. Since NaCl dissociates into two ions – sodium and chloride – 1 molar NaCl is 2 osmolar. Thus, NS contains 154 mEq/L of Na+ and Cl. It has a slightly higher degree of osmolarity (i.e. more solute per litre) than blood (However, if you take into account the osmotic coefficient, a correction for non-ideal solutions, then the saline solution is much closer to isotonic. Osmotic coefficient of NaCl is about 0.93; therefore 0.154 × 1000 × 2 × .93 = 286.44) Nonetheless, the osmolarity of normal saline is a close approximation to the osmolarity of NaCl in blood.

One litre of 0.9% Saline contains:

 

 

or for us normal people, thats about a teaspoon of salt in a pint of water :D
