Unknown Ionic Compound ILI#3 Abstract: In this laboratory investigation‚ 8 solutions were combined with each other and an unknown liquid #1 in order to identify the ionic compound in the unknown solution. The students performed an experiment in which the reactions between each substance were compared to the unknown solution #1’s reactions and the color of each solution was compared to help find the unknown #1. The unknown ionic compound was identified to be Zinc Sulfate as the reactions between

Ionic bonding is known as a type of chemical bond where the valence electrons are lost from one atom and gained by another. This exchange results in a more from one atom and gained by another. When an atom gains or loses electrons while being bonded with another atom an ion is formed. This bond causes an atom to become either a positive or negative ion. Electrons have a negative charge‚ meaning that if an atom loses an electron‚ the amount of protons are greater than electrons. This makes the atom

Lab: Ionic and Covalent Bonds Objectives • Understand the differences between ionic and covalent bonds. • Connect ionic and covalent bonds with physical properties of matter. Introduction Sugar and salt look so similar that most people cannot tell them apart without tasting them. Chemically‚ white refined table sugar‚ sucrose‚ and salt are very different. An ionic bond between a positive sodium ion and a negative chloride ion creates a molecule of sodiumchloride (NaCl). Covalent bonds between

Introduction For the last week‚ specific tests had to be applied to determine the unknown solid that was given out randomly. Physical tests‚ solubility test‚ characteristic tests‚ NMR spectrums‚ and IR spectrums were all utilized to distinguish the identity of the solid. These assessments and a couple additional tests will be utilized again to determine the unknown liquid that was given to us in class. The other characteristics that will be looked at will be the boiling point‚ refracted index‚ and

How do ionic bonds form? Transferring the electron forms an ionic bond. After transferring the electron‚ the two atoms become ion n will attract together because they have the opposite charges. Then an ionic bond is formed. How do covalent bonds form? A covalent bond is for sharing of electrons. I remember it like co-existing electrons to share (Eg H20). It is usually between two non-metals. Which compound‚ sugar or salt‚ is a better conductor of electricity? Explain your answer. Salt

Reactions in Aqueous Solutions: Metathesis Reactions and Net Ionic Equations Introduction: Metathesis or double decomposition reactions are a reaction in which two compounds react to form two new compounds‚ with no changes in oxidation number. The ions of two compounds exchange partners. AX + BY AY + BX This reaction can occur between two inorganic salts when one product is insoluble in water‚ driving the reaction forward. A typical example is as followed and is considered a molecular equation
