Get Charged Up Lab Report

Abstract
Get Charged Up

Magnesium ribbon was reacted with Hydrochloric acid in three different experiments to determine the charge on a metal ion. After running multiple tests in the three different procedures, the Crystallization method proved to be the best method for determining the charge of the metal ion by using mole to mole ratio.
Introduction
The objective of the Get Charged Up lab was to determine the charge on a metal ion reacting with HCl by determine the mole ratio in a reaction by determining the amount of excess reactant, amount of product, and amount of hydrogen gas produced as well as finding the best research method to determine the charge.
To accomplish this, three different methods …show more content…

All three graphs had a positive correlation in terms of the x and y relationship.
Table 1. Crystallization Method

There is a positive correlation between the moles of Mg compared to Moles of Cl in salt. The correlation coefficient of .7964 relates to the accuracy of the data and the slope of the line (1.981x) relates to the mole ratio between the two substances.

Table 2. Ideal Gas Law Method

There is a positive correlation between the moles of Mg compared to Moles of H2 produced. The correlation coefficient of .9956 relates to the accuracy of the data and the slope of the line (0.8167x) relates to the mole ratio between the two substances.
Table 3. Titration Method

There is a positive correlation between the moles of Mg compared to Moles of H+ reacting with Mg. The correlation coefficient of .9999 relates to the accuracy of the data and the slope of the line (1.7923x) relates to the mole ratio between the two substances.
Discussion
The best method was the crystallization method for determining the charge on a metal ion. The best method is the most accurate method. This was determined by looking at the correlation coefficient, y-intercept, and slope of the line on the respective graph and seeing the trend of positive correlation. The crystallization method had a slope closest to what it was supposed to be (1.981 compared to 2.000) yielding that this method was the most accurate at determining the

    Static Electricity Everything is made up of tiny particles called atoms. The atoms are made up of even smaller parts called protons, electrons and neutrons. Protons have a positive charge (+), electrons have a negative charge (-) and neutrons have no charge at all, they are neutral. Atoms normally have the same amount of electrons and protons, making them neutral and having no charge. When rubbing things together, electrons can move from one atom to another, resulting in some atoms having extra….
