Ionic Compound Lab Report

In this Crash Project, there will be two types of chemical equations being used in order to discover the following: The Murderer, The Murdered Victim, The compound that caused the crash, The passenger with the explosives, and the identity of the terrorist. The chemical equations is the Molecular Formula and the Empirical Formula. The Molecular Formula is a formula that identifies the amount of atoms present in a certain element in one molecule of a certain compound. On the other hand, the Empirical Formula is a formula that identifies the distribution of the elements present in a specific compound, rather than the actual amount of atoms in the compound.

When calcium chloride, sodium bicarbonate, and phenol red are put into a bag and mixed up the type of reaction that occurs is a chemical reaction for the following reasons. Things that indicate that a chemical reaction has occurred are color change, formation of precipitate, formation of gas, and energy transfer in which three of them took place in the reaction of calcium chloride, sodium bicarbonate, and phenol red. The three indicators in this experiment were: a color change, formation of gas, and an energy transfer

The unknown ionic compound was composed of translucent crystals. It had no odor, was soluble in water, and its electrical conductivity in water was measured at 1.66V, as indicated in Table 1. The compound burned a bright red during the flame test consistent with the flame signature of calcium, as indicated in Table 2, and along with the fact that the compound was soluble in water, this helped us to eliminate the possible presence of the poorly soluble salts (Cooper, 2008). However, tests for these anions were still performed.

Table 2: Consists of color extract taken from a red cabbage for a natural indicator. The pH reading that was measured by using the pH meter and the result of the pH reading to determine whether the solution was acidic or basic.

Being able to identify an unknown compound is incredibly important as it would allow chemists to synthesize compounds in various reactions and identify the products. Although balancing an equation is always possible, full and complete reactions based on a chemical equation are not possible in practice, and as such, being able to identify what was actually created would be important. Additionally, it would be important to

During this investigation the question we looked to answer was: what are the identities of the unknown compounds? In an effort to answer the question, our group designed a method in which the relationships between the unknown compounds in plastic bags were compared so that their identities could be determined. The mole (mol) provides a measure of the number of atoms present in the sample of a compound. One mole of an element or compound contains

As a result of this lab experiment, the hypothesis is attested to be precise as the ionic compounds did go through a double displacement reaction. The purpose of this experiment was to establish what occurs when two pairs of compounds react with one another. The information collected while doing the lab has allowed more knowledge to be obtained, as one can visibly see the changes happening and different signs of chemical changes. The cations and anions in the ionic compounds have successfully exchanged places with one another, creating the compounds with the different properties evident in the observation given. For example, precipitates were visible in almost all reactions in this experiment. Therefore, this lab experiment was held to demonstrate

The purpose of this lab was to experimentally and scientifically ascertain the percentage of oxygen in Chem B at Woonsocket High School. It was hypothesized that if the percentage of oxygen is measured experimentally in Chem B at Woonsocket High School, then it would be higher than the percentage of oxygen in dry air, which is 20.95%, because the air is not dry due to moisture in the air from people breathing and the altitude of where the experiment takes place may affect it as well.

This is done through a change in temperature. Over time, two objects that are in direct contact will

INTRODUCTION: The goal of this experiment was to perform tests to determine identify an unknown ionic compound. Our group was given compound #107, an unidentified white powder with no other information prior to testing. Our group was to assist in identifying the compound so it could be disposed of properly.

The purpose of this lab was to find out how gaviscon reacted with different salt solutions. Sodium Alginate is a compound that forms with the Gaviscon and forms a “raft” and blocks all the stomach acid from traveling up the esophagus.

Many ionic compounds can be separated from an aqueous solution in solid form using evaporation and centrifugation techniques. Evaporation results in separation by phase, as a liquid is vaporized, and centrifugation results in separation by weight. Evaporation was used to isolate the insoluble compound sodium sulfate as a solid. Centrifugation was used to isolate the soluble compounds silver chloride, barium sulfate, and zinc hydroxide as solids. To

Stoichiometry and Determining the Limiting Reagent Abstract: Four chemical reactions will be done using different ratios of mixture between calcium chloride and sodium carbonate. The mixture of these two substances produces the precipitate calcium carbonate, which will be separated using filtration. After observing the tubes and collecting data, the limiting reagents were deduced from observing which amount of substance had the least amount of moles. It was found that in trials one through three, the limiting reagent was calcium chloride and in trial four, the limiting reagent was sodium carbonate.

Purpose: The purpose of this lab is to be able to perform four different types of chemical reactions. With the information gained from these reactions, identify the products of the reactants with be identified and balanced equations for the reactions observed will be written.
