Thus, mineral acids, bases and salts, which are polar, tend to be much more soluble in water, which is polar, than in … Solute Polar or Nonpolar H2O or CCl4 O2 (g) C6H12O6 (s) (glucose) CO2 (g) KCl (s) Question Water is a polar solvent and carbon tetrachloride (CCl 4 ) is a nonpolar solvent. While it is not nearly as soluble in methanol as in water, some will dissolve. Is sucrose soluble in hexane? substances are generally either. For example, water is polar. Just to explain the opposite idea: a polar solute in a nonpolar solvent. A better general statement is that soluble salts tend to produce ions when they dissolve in water. This preview shows page 1 - 4 out of 4 pages. so we did a lab and idk if this data makes any sense the times are how long it took for them to melt.. and I dont understand why some compounds are soluble in water and some in methanol and some in both or did I record data wrong and they are supposed to be soluble in EITHER water or methanol?? The amount of solute, which can dissolve in a given amount of solvent depends on the nature of the solute and solvent. Basically, polar solvents dissolve polar substances, and non-polar solvents dissolve non-polar substances. Lastly the lab requires allows students to qualitatively compare the melting points of both ionic and molecular compounds. Find answers and explanations to over 1.2 million textbook exercises. chemical nature of the solvent and solute will impact the resulting solution. these solutions will conduct electricity and have positively and negatively charged ions in the solution. Nonpolar solutes dissolve more readily in nonpolar solvents than polar solvents. . All of these principles come into play with chromatography. Therefore, water will be a better solvent for other polar compounds. Classifying Types Of Solutes and Solvents Introduction The main purpose of the lab is to test the solubility of different solutes in varieties of solvents. Explain why water is called a polar covalent molecule? Yet the polar bonds in CuCl2 have 33% ionic character, and the solid is a polymer. Answer Save. non-polar solvents. explain which solvent below you would use to remove road salt stains from a pair of jeans. This concept is often expressed as “Like dissolves like. HCl has none of the hallmarks of an "ionic" compound, yet it dissolves in water to make ions. Nonpolar solvents can dissolve nonpolar solutes with the help of weak van der Waals - London forces if the solutes have similar internal pressure. Polar and non-polar solutes and solvents: help these questions are urgent plz? polar solvents dissolve polar solutes and non-polar solvents dissolve non-polar solutes). As for your lab, MgCl2, KI and NaCl are soluble salts with bonds with relatively high ionic character. This explains why methanol is completely miscible with water. In chemistry, it is the charge separation in a molecule that has atoms or groups of atoms with different electronegativity. spontaneous combustion - how does it work? Nonetheless, CuCl2 dissolves in water to make Cu2+ ions and Cl- ions. Nonpolar substances tend to be soluble in nonpolar liquids. A non-polar solvent will be able to carry a non-polar solute through a polar stationary phase rapidly, but a non-polar solvent will not be able to carry a polar substance through a polar stationary phase very well at all. STATION 1: “Oil and water do not mix.” We all know that. Answer and Explanation: The molecules of water are polar in nature due to the presence of a positive end as oxygen and a negative end as hydrogen. Another is copper(II) chloride, CuCl2, what some would say is an ionic compound. Refer: Because water molecules are polar, they interact with the sodium and chloride ions. Lab Procedure 1. Manual. Chemistry 11 Experiment 16A-Polar & Non-Polar Solutes and Solvents Name _ Experiment 16A-Polar & Non-Polar Solutes … As a metaphor, it is often used to explain why relationships between opposites are difficult. Bc frankly, I do not see any patterns so maybe I recorded data wrong? I have several questions here, please help out with anything you are able to answer bc my chem teacher does not teach us anything at all. Carefully fill one beaker with 20-30ml of water using either the faucet or a graduated cylinder. They will help you answer the analysis questions that follow.
