Does The Magnesium Ribbon Verify The Meaning Of Ph

687 Words3 Pages

Introduction
On Monday, in class, we executed an experiment. The objective is to…

Problem Question
Before completing the experiment I have to choose a problem question. I have decided to answer the following question to solve a problem; which of the three unknown concentrations of acid is the strongest? I have chosen this problem question because it is a fulfilling question based on the aim of this experiment.
To substantiate the question with background research before completing the experiment, I would have to understand what acid is. Additionally, I will ask myself how I will know which acid is the strongest and how strong the acid has to be to make the Magnesium ribbon dissolve.

Background Research
The meaning of pH is generally the measure of the …show more content…

It is proved that magnesium ribbon does dissolve when dropped into a test tube of hydrochloric acid, but also hydrochloric acid mixed with water. As stated by http://www.engineeringtoolbox.com/acids-ph-d_401.html, hydrochloric acid has a pH level of 0,1 to 2, which is clarified as a strong acid. The collision theory says that as more collision in a system occurs, there will be more combinations of molecules bounding into each other. If there are a higher number of in a system, more combinations of molecules can occur. The reaction will go faster and the rate of the reaction will go higher. There are five things that affect the overall speed of the reaction and the number of collisions that can occur. Examples are concentration, temperature, and the amount of magnesium.
We also know that Magnesium metal (in form of a ribbon or powder, also called active metal) reacts with acids rapidly than water liberating hydrogen gas. For instance, magnesium metal reacts with hydrochloric to form magnesium chloride salt and hydrogen gas, as claimed by

Some factors that influence the speed of a chemical reaction are: (1) surface area of starting reactants; (2) concentration of reactants; (3) temperatures. The particle theory states that a solute dissolved takes place at the surface of the solvent and the larger the surface area of the particle the longer it will take to dissolve. The smaller the area the faster it will

In the second lab “Water down a String”, when I had first attempted to pour the water down the string, which was dry, it had failed and did not form into beads at first. After I had dampened it, and did a second trial, the water formed into beads and rolled easily down the string and into the second beaker. This again goes back to water’s high surface tension,

Alka Seltzer Experiment

Introduction During this lab, students observed that not all substances dissolve at the same rate. Many factors involved including the independent and dependent variables affect how distinct substances dissolve. Overall, the chemical reaction, “the amount of reactant that changes the product in a given time”, played an important part in this experiment, when proven how a substance can change into another element by either emitting or absorbing energy. (Tro, 2018).

How Does Atomic Radius Affect The Reactivity Of Elements

449 Words | 2 Pages

First of all reactivity is how fast electrons can be gotten rid of. Atomic radius is a major factor which illustrates reactivity based on the size of orbitals located in the atoms. Looking at the periodic table, I can tell that by going left and right and up and down, the atomic radius increases. Hence, calcium would have a higher atomic radius than magnesium which would also be higher than aluminum. Atomic radius affects the reactivity of elements because if an element has a small atomic radius, the electrons in the outermost orbital will be very close to the protons near the nucleus, making the protons have a tighter grip on the electrons ultimately making it both harder and slower to remove electrons.

During the standardization titration, there were two attempts made at dissolving the calcium carbonate. On the first attempt, sodium hydroxide was added along with the magnesium but would not dissolve completely. On the second attempt, an extra 5 mL of sodium hydroxide was added to help dissolve the calcium carbonate. After the solids dissolved over a heated stove, the magnesium was added. All of the water hardness comes from the Ca2+ of the calcium

Four Drinking Categories Lab Report

1751 Words | 8 Pages

The methods used in this lab experiment consisted of having four different drinking categories. These categories were non-drinkers, Coke, Gatorade, and water; the subjects will be chosen randomly to drink one of the drinks and then void 30 minutes after. After voiding, the subjects will have measured their urine temperature, urine volume, calculate specific density, urine pH and urine flow rate. After the calculations are done, the subjects will use the Labstix strips to measure if their urine tests positive or negative for blood, ketones, glucose, and protein. In my hypothesis I will expect water to have the greatest urine volume and flow rate, then all other drinks (Gatorade, Coke, and non-drinkers).

The Biological Temperature Of Catalase

750 Words | 3 Pages

Reactions in the human body produce hydrogen peroxide as a product (1). Since hydrogen peroxide is poisonous to the human body, catalase catalyzes hydrogen peroxide into water and oxygen (2 H2O2 → 2 H2O + O2) (1). According to the collision theory, a reaction can only occur if particles collide with sufficient energy to overcome the activation energy and with correct geometrical orientation (3). Increasing temperature increases the kinetic energy of the particles which means that an increase in temperature will increase the speed of the hydrogen peroxide and the catalase molecules which

How Does Acetic Acid Effected By Vinegars Temperature

1958 Words | 8 Pages

Introduction: In this experiment vinegar is the household product being tested. This experiment is being used to see whether or not the acidity of vinegar is effected by vinegars temperature (fridge temperature, room temperature or heated). This will be done using titration methods (slow addition of one solution of a known concentration (called a titrant) to a known volume of another solution of unknown concentration until the reaction reaches neutralization, which is often indicated by a colour change) with Vinegar as the acid, Phenolphthalein as the indicator and Sodium Hydroxide as the base. Acids and Bases can be defined by three different definitions, the Arrhenius definition, Brønsted-Lowry definition and Lewis definition.

Lab Report On Acid Base Titration

Strong acids and strong bases are strong electrolytes and are assumed to ionize completely in the presence of water. Weak acids however, only ionize to a limited extend in water. Any weak or strong acids when in contact with any weak or strong alkali will start to undergo neutralization regardless of their volume. When an indicator which is present in the acid-base mixture and have experienced colour change, it indicates that the mixture is in right proportions to neutralize each other and is also known as the equivalence point.
