acidify with 5 mL of 3M sulfuric acid. After the acid‚ 5 mL of starch was immediately added into the solution. The solution didn’t turn into a blue color‚ so a blank correction was not needed for the standardization and analyzes volumes. After determining that a black correction is not needed‚ the standardization of thiosulfate was performed. To standardize the thiosulfate‚ about 2.00 grams of potassium iodate was dried in an oven. After drying the potassium iodate for an hour‚ it was taken out and in three

and will tweak different attributes of it with borax‚vinegar‚baking soda and water. Borax is a widely known as a laundry detergent and can be used in many ways like a water softener‚disinfectant‚mouthwash and so many other numerous things i can’t even count. The reason for this in this experiment is it reacts with the glue to make slime‚what it does it squishes the molecules in the glue to make polymers which make the slime .it depends on how much borax goes in the more there is the more solid it

Acid-Base Titration Pre-Lab Discussion In the chemistry laboratory‚ it is sometimes necessary to experimentally determine the concentration of an acid solution or a base solution. A procedure for making this kind of determination is called an acid-base titration. In this procedure‚ a solution of known concentration‚ called the standard solution‚ is used to neutralize a precisely measured volume of the solution of unknown concentration to which one or two drops of an appropriate acid-base

Borax‚ sodium phosphate‚ and ammonium chloride‚ are all ionic compounds. This can be shown based on the electronegativity difference between the atoms‚ and the fact that it involves metals and non metals. The rest of the solutes are covalent bonds. Iodine and paraffin are both non polar molecules. This can be shown by the eletronegativity difference‚ and the shapes the molecules make‚ which show that they are very balanced molecules. Sugar‚ citric acid‚ urea‚ and borax‚ are all polar
