Solid and Melting Point Essay(2pts) Indicate the redress waste container for the following obscuresa. hexane non-halogenated organicb. 10% NaOH aqueousc. methylene chloride (dichloromethane) halogenated organicd. magnesium sulfate unattackablee. sodium hypochlorite halogenated organic2. (1pt) Describe the proper(a) way to separate ground glass joints if they become stuck.The proper way to separate ground glass joints is to hold the two pieces of glassw atomic number 18 with paper towels so that your hold are touching as close to the joint as possible and pull with a staunch grip. Try to loosen with a slight twisting motion. If that does not work try to tap with a wooden handle and try to pull apart. Lastly you can heat the joint with hot piddle or steam bath, but to be careful not to over heat.3. (1pt) What is a solute? What is a dissolving agent?A solute is the solid that is dissolved in a liquid. The solvent is the liquid in which something is dissolved.4. (1pt) Wh at is the purpose of a water trap (used during vacuum filtration)?The purpose of a water trap is to prevent filtrate from being sucked into the vacuum system.5. (2pts) What is the difference between crystallization and precipitation of a product? List three differences.crystal forms crystalline solids while precipitation produces amorphous solids. Crystallization is slow and a pure compound comes let out of solution and precipitation is fast and a mixture of compounds falls out of solution. Crystals have an ordered social structure than amorphous solids and are harder to produce.6. (1pt) What will happen if you choose a solvent whose boiling point is high than the liquescent point of the compound to be crystallized?The solvent would boil out before the compound could melt.7. (1pt) How does the melting point of a product help determine its purity?The purer the material the higher its melting point and the narrower its melting point shed is. The range should fall in to the melti ng point range of what the substance you are determining its purity for.8. (1pt) Generally describe how to predict solubility.Like dissolves like. The solvent/solute molecules are structurally similar so the solute will dissolve in the solvent.
