Ionic Reactions Introduction: Today we are going to observe the chemical changes when mixing two solutions. Some will change colors‚ produce gases proving if the solutions are soluble or insoluble. Materials and Methods: I first pulled out the small wells and place two drops of the Cobalt (II) Nitrate in seven of the wells. I then moved to the next row and placed two drops of Copper (II) Nitrate in the next row‚ into seven of the wells‚ and so on with the other three Nitrates. I then cut off

Writing ionic equations for redox reactions You can split the ionic equation into two parts‚ and look at it from the point of view of the magnesium and of the copper(II) ions separately. This shows clearly that the magnesium has lost two electrons‚ and the copper(II) ions have gained them. These two equations are described as "electron-half-equations" or "half-equations" or "ionic-half-equations" or "half-reactions" - lots of variations all meaning exactly the same thing! Any redox reaction

The Aim of the experiment: In this experiment I will investigate the relationship between the concentration of the hydrochloric acid and the rate of a reaction. To find this out I will react different concentration of hydrochloric acid and magnesium‚ from there I will monitor the gas (hydrogen) produced and analyse the results. Prediction: I predict the higher the molarity of the hydrochloric acid the faster the rate of reaction therefore the quicker the gas will be produced in the specific

Define and describe ionic and covalent bonds. An ionic bond is a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions. A covalent bond is the chemical bond that involves the sharing of pairs of electrons between atoms. A compound is made when two or more atoms form a chemical bond‚ linking them together. The two types of bonds are ionic bonds and covalent bonds. In an ionic bond‚ the atoms are bound together by the attraction between oppositely charged

Students wear glass have slower reaction times than students don’t wear glass. Beginning with the class was divided into three groups‚ two groups of five students and one group of six students. Each group of students got a ruler from teacher and the result table. The ruler was held

When ionic solids dissolve‚ they divide to give their positive and negative ions that make up the solids. These ions become hydrates and have the same relative proportions when in solution and when solid. The more the solid dissolves‚ the more the ion’s concentration increases. This increase and build-up allows for the reverse reaction to occur. In this phase of the reaction the ions crystallise out in order for the reaction to have a greater chance of occurring. Eventually the rate of

Ionic compounds are formed when a metal and a non-metal join together. When sodium metal is dropped into a gas jar of chlorine gas the elements react violently to form a new compound called sodium chloride joined by ionic bonds. To understand how this process works‚ we must grasp an understanding of what an ion is and what an ionic bond is. An ion is an atom that has an electric charge and is created when an atom (or a group) gain or loses electrons. (It has an electric charge due to the imbalance
