Essay on Ionic and Covalent Bonds Lab

What buret reading should you record when the liquid level is as shown in Figure 2?

2. Write a statement to explain the molecular composition of the unknown solution based on the results obtained during testing with the Biuret solution and each sample solution.

    C.grains of sand-sized particles.     D.gypsum.   Answer Key: A   Feedback: The correct answer is A. silica.     Question 19 of 33 3.03/ 3.0303 Points Which of the following is a diagnostic feature of Specimen #16?

III. For observation 1 and 2, pour 1 cup of water into a pan and place on stove on high heat. For observation 2 add

12) The 8-11 steps for each of the remaining bottle was repeated, the sugar concentration was adjusted accordingly.

Typically an ionic bond occurs between one metal and one non-metal ion. One atom borrows one or more electrons from another atom. An ionic bond is a type of chemical bond that occurs when one atom loses an electron to form a positive ion and the other atom gains an electron to form a negative ion, which then result in attraction.

2. Describe the three different types of bonds, providing examples of molecules formed through each type of bond. (3 points) Covalent bond, methane. Ionic bond, table salt. Hydrogen bond, water.

8. Repeat step 7 with H2SO4, except that you should use a 10 mL graduated cylinder of H2SO4 and adding 15 mL water.

Place the beaker on the hot plate, place the thermometer in the beaker and set the hot plate to 5oC.

Aqueous solutions of ionic substances will be experimented with in this Ionic Reactions lab. Aqueous solutions are solutions that water is solvent. After ionic substances dissolve in water, ions separate and become surrounded by water molecules. When these ion separate, its called dissociation.

1. Using the information provided in the Introduction and your observations from Part 1, hypothesize as to the type of electrolyte the following solutions would be. Justify the hypothesis from a chemical standpoint.

After completing the lab, we will be able to identify covalent, ionic, and hydrogen bonds. Hydrogen bonds are the weakest between all the three types of bonds we will be observing and it occurs between hydrogen and oxygen atom or nitrogen atom; hydrogen bonds are a type of dipole-dipole bond. A dipole-dipole interaction occurs because of polar molecules. We should know that the bond between hydrogen and oxygen in a water molecule is covalent. Another example, of covalent bond is the bond between all the atoms that compose ethane. Another objective that we will observe is solubility, the lab mentions. An example, of an ionic bond is NaCl, this is an ionic bond because the Na+ and Cl-, the sodium atom (cation) gives a pair of electrons to the

There are many properties that distinguish an ionic compound from a covalent compound. The electrical conductivity of the compound when it is dissolved in water can assist in classifying the compound as ionic or molecular. If the compound possesses the qualification of an electrolyte, it can be identified as an ionic compound, seeing as ionic compounds are capable of conducting electricity when dissolved in water.

Ionic bonding is a type of chemical bond formed between two ions with opposite charges. Ionic bonds are formed between a metal and a non-metal. Non-metals are stronger than metal and can get electrons easily from the metal. These ions attract each other and create an ionic bond. Ionic bonds are also known as electrovalent bonds. Ionic bonds form their bond when opposite charged ions in a chemical compound have an electrostatic attraction. Even thought Ionic bonds still hold molecules together, they are weaker than covalent

The overall goal of this activity is to provide the students with a diagram that can help them learn and memorize the different characteristics associated with chemical bonding. If students have difficulties differentiating the characteristics associated with covalent and ionic bonding, they will suffer with future topics and other branches of chemistry. Ionic bonding is a crucial topic to understand within general chemistry reactions. Covalent bonding is a root within Organic and Biochemistry that needs to be understood in order to fully understand the theories and concepts discussed in both forms of chemistry.
