Ion

The positive Na+ ions were attracted to the oxygen (negative) end of the water molecules, and the negative Cl- ions were attracted to the hydrogen (positive) end of the water molecules. As an end result, the ionic bond between the sodium and the chloride was broken. CuSO4(s) ⇔ Cu+2(aq) + SO4-2(aq) Like the sodium chloride, the copper sulphate was split into its individual ionic components. The positive Cu+2 ions were attracted to the oxygen (negative) end of the…

Topic 1: Chemical bonding 1.True or False: An Ion is when an atom gains or loses an electron. 2.What is a Cation?

It did this because the chlorine ion of HCl was able to bond with silver or lead, leaving the other cation in the liquid solution that was decanted and set aside for Part B.1 In Step 5, the sample with either silver or lead was heated in a water bath. This step was essential as heating the solution broke any ionic bonds within the…

chemical and physical properties but also what the unknown compound might react with to form other compounds. After performing the four anion tests, a positive identification was able to be made showing that the unknown compound contained a chloride ion since a white precipitate was formed from the reaction (Table 1). The sulfate, nitrate, and carbonate tests all yielded negative results when no precipitate was formed. The reaction of the chloride anion is as follows: Cl- + AgNO3 -->…

dialysis tubes were taken out from the graduated cylinder. The solutions inside of graduated cylinder were used to perform Benedict’s test, IKI test, and biuret test. For the solutions that had NaCl, and MgCl2 dialysis tubes were used chloride ions and magnesium ions methods to detect. In this experiment, the independent variable was the different amount of solutions; the dependent variable was whether or not these solutions would pass through. The controlled variables were the same amount of…

Introduction In order to create a compound, there must be two or more atoms that bind together. These atoms may be made up of different elements, or some may be the same. There are two main ways that atoms bind together- covalently and ionically. In a covalent bond, two non-metals of similar electro negativities come together to share electrons with each other. These electrons come from the outer-valence shells, and are shared in a way so that both electrons can have satisfactory shells,…

temperatures. The attractive force increases as the charge increases, but the distance stays constant, but the attractive force decreases as the charges stay constant, but the distance increases. Since in these ionic compounds, the ions have a strong attraction towards other ions, the boiling temperature increases due to the increases in thermal energy needed to overcome the new intramolecular forces. The fact that these ionic bonds are highly polarized is reflected in extremely high melting…

There are several physical and chemical methods, of which the simplest method involves the reduction of the metal salt AgNO3 by NaBH4 in water. Wiley and his coworkers synthesized three different shapes of silver nanoparticles using chemical method, in which ethylene glycol used as both solvent and reducing agent [5]. This group synthesized cubic silver nanoparticles by reduction of silver nitrate (AgNO3) with ethylene glycol in the presence of Polyvinylpyrrolidone (PVP) and HCl. After synthesis…

In Fig 4 pore size distribution profiles of the Y and MY is observed. By the BJH method, which uses desorption branch of the nitrogen isotherm in order to calculate the pore size distribution and the adsorbed volume[12], the pore size in the range of only 1.4 nm could be seen in Fig. 4a. Presence of various distribution of pore size is the manifest of the related BJH of the MY zeolite in Fig. 4b. As can be seen there are the pore size distributions from 1.2-6 nm in which the pores in the range…

Identifying Unknown Substance. Examining the physical characteristics of the available compounds in the lab was how possible compounds were eliminated from any or further testing. Based on how the compounds physically looked, it was almost for certain that calcium chloride was the unknown compound. However, another compound was used to test as well (ammonium chloride) since relying only on physical characteristics alone would not allow for proper experimentation. The unknown ended up being…
