During the experiment, observations were made about their physical appearance. In part I, reaction one produced a blinding, bright white light when the metal burned and the metal turned into a white powdery substance. For reaction two, there was no reaction at first and it took a long time for it to react, but then bubbles started to form around the magnesium ribbon and the substance turned into a pink-yellowish color around the magnesium strip when it was placed in the 150 milliliters beaker. The physical observations of reaction three was the magnesium strip started to form bubbles around it and it seemed to protrude from the magnesium strip itself. Reaction four, when reacted, bubbles started to form around the magnesium strip, it started …show more content…
An oxidation-reduction, otherwise known as redox, is a type of reaction that involves the transfer of electrons between two reactants. These reactions were identified as a redox reaction because of how they turned into a different color, signifying there was a transfer of electrons which changed the physical appearance of the solution. In order for the reaction to be redox, a chemical substance has to be used up in the process and it has to create a new chemical substance. It also had to have a transfer of electrons between each other, if there is no transfer, then the reaction is not a redox chemical reaction. In reaction one, the magnesium reactant was oxidized because it lost electrons, whereas the oxygen reactant was reduced because the reactant had a gain of electrons. Reaction two’s magnesium reactant was reduced because it had a gain of electrons, while the water reactant was reduced because it lost electrons. The third reaction’s magnesium reactant lost electrons, so it was oxidized. The hydrochloric acid found in this reaction was the reactant that was reduced because there was a gain of electrons in the chemical reaction. All of the other reactions also had reactants that were either reduced or oxidized in the chemical …show more content…
An acid-base reaction is a chemical reaction that utilizes an acid and base that react to form a neutral substance because the acid and base cancel each other out. When they are formed, they tend to produce a salt. The hydrogen ions and hydroxide ions when combined, tend to form water. In order for the reactant to be an acid, it has to conduct electricity, change a blue solution to a red tint, have a sour taste, react with bases to neutralize their properties, and it has to react with active metals to liberate the hydrogen ion in an acid. In order for a reactant to be a base, it has to conduct electricity, change a red solution to a blue solution, have a slippery feeling to it, and it has to react with acids to neutralize their own properties. Reactions nine, eleven, twelve, and fourteen are all acid-base chemical reactions because the reaction involves either an acid or base. There is also a color change, or bubbles start to form from all of the reactions that were identified as an acid-base reaction. Heat is also detected in all of the reaction signifying it is conducting some sort of energy or electricity. Therefore, reactions nine, eleven, twelve, and fourteen are all acid-base chemical reactions because of the chemical properties that they
