Reactivity starting from the least reactive. Li‚ Na‚ K c) A piece of sodium was dropped in a trough containing water. i) Describe what you would see. Sodium melts almost at once to form a small ball that dashes around the surface. . If the sodium becomes trapped on the side of the container‚ the hydrogen may catch fire to burn with an orange flame ii) Write a word and symbol equation for the reaction. sodium + water → sodium hydroxide + hydrogen 2Na + 2H2O → 2NaOH + H2 iii) what would be the

Section 3: Procedure In this experiment‚ I observed substances in their natural state‚ and recorded their apparent physical properties. I then tested the substances to determine how they react when their natural environments were altered. The pure substances were tested to see

1. Standarization of NaOH with Potassium Hydrogenphthalate (KHC8H404) The hygroscopic nature of NaOH requires its solution to be standardized with a stable primary standard such as potassium hydrogen phthalate. The exact molar concentration of NaOH solution can then be accurately determined. 1.1) Prepare the stock NaOH solution by dissolving about 4 g of NaOH pellet in 100 mL of deionized water. Note that NaOH is a hazardous chemical which is corrosive to skin and irritant to eye‚ be cautious and

I will be using ¼ cup of ammonium sulphate fertilizer and ½ cup of sodium chloride concentrations salt‚ rock salt (halite)‚ and calcium magnesium acetate salt (Peeples‚ 1990). The last and final ingredient I will need is three different types of grass sod‚ St. Augustine grass‚ Bahia grass‚ and Buffalo grass cut in 5 inches

There are different kinds of compounds‚ ionic‚ covalent‚ and acidic and over all of this the atoms making up the compounds are either binary or polyatomic. The simplest compounds to name are binary ionic compounds‚ for example NaCl‚ which is named Sodium Chloride. Na having a positive oxidation number goes first followed by Cl which having a negative oxidation number goes last and is changed from Chlorine to chloride the -ide indicating its negative charge. Of course‚ the
