    #8: Ionic Reactions Purpose: In this lab we will work with aqueous solutions of ionic substances and determine if they are soluble. If the solution appears milky than it is known as a precipitate reaction‚ meaning it is soluble‚ and that the ions separated and became surrounded by water. Precipitates in this experiment are electrically uncharged. To identify which compounds are soluble or insoluble we can check the chart in the textbook containing solubility rules and tables. The goal of

    Determine the cation and anion in an unknown solution All salt solutions have both positive (Cations) and negative (Anions) ions dissolved in it. In this experiment you will observe chemical reactions to determine the presence of specific anions and cations. Compare your observations with the reactions of the known solutions and the unknown solution to determine the ions present in the unknown solution. You will use a flame test for the cations‚ Na+‚ K+‚ and Ca+2 Perform qualitative tests for

    and the product energy remain the same while the activation energy is lowered. Arrhenius concept is about the acids and bases split into ions when they dissolved in water. The Arrhenius acid-base concept classifies a substance as an acid if it produces hydrogen ions H+ or hydronium ions in water. A substance is classified as a base if it produces hydroxide ions OH- in water. Arrhenius concept focuses on what the chemical contains or what is there in solution.
