Potassium hydroxide

Decompositions can have up to 4 potential ways it can be balanced in a chemical equations while only one equation can be correct. The purpose of this lab is meant to investigate which decomposition equation is correct. The guiding question for this experiment is “Which balanced chemical equation best represents the thermal decomposition of sodium bicarbonate?” given the equations NaHCO3 → NaOH(s)+CO2 (g), 2NaHCO3(s) → Na2CO3 +CO2(g)+H2O, 2NaHCO3 (s) → Na2O (s) + 2CO2 + H2O, NaHCO3 (s) → NaH (s)

The purpose of the lab is to determine the molar concentration of acidic acid in vinegar by titrating it with a solution of NaOH. The sodium hydroxide is a basic solution. When adding it to a acetic acid, a neutralization occurs. An indicator is added to the solution. The indicator is a dark pink color. When the NaOH is added, it makes the solution more basic and causes the solution to turn light pink. The experiment is successfully completed when the right amount of indicator is added, and It turns

Benzophenone (1.00g, 0.0054 mole) was measured and added into a 100 mL round-bottom flask. Next, 95% of EtOH (15 mL) was measured and placed in the round-bottom flask and a stir bar was added. The mixture was heated on a sand bath until the benzophenone dissolved completely. The round-bottom flask was removed from the sand bath and it cooled for a few minutes. A preliminary TLC was conducted with 20% ethyl acetate and 80% hexanes solution. Next, NaBH4 (0.100g) was measured and added to the solution

Titration is a technique that is used to determine and analyze the concentration of a substance. It is based off of mole ratios between the two substances taking part in the lab. Burets are used in the titration of substances, which are large glass tubes with a valve attached to the bottom to allow the specially measured amount of substance into another. The amount of each substance must be very precise and be recorded properly. The analysis of these reactions are usually simplified to a 1:1

Titration what is that you may be asking yourself. Well a titration is a method of analyzing that will allow you determines the endpoint of a reaction and therefore the quantity of the reactants in the flask A buret is used to deliver the second reactant to the flask and an indicator or pH Meter is used to detect the endpoint of the reaction. Also just so you know a titrant is the know solution that is added and a the analyte is the unkown solution until the reactanc is complete. In order to do

Observing Double Displacement Reactions Purpose: The purpose of the lab is to determine and observe the different double displacement reactions that occur when certain reactants are mixed. Double displacement reactions will be classified with the use of indicators. Introduction: Chemical reactions occur very often in people’s everyday lives. There are six main types of reaction. These include decomposition reactions, synthesis reactions, single-displacement reactions, double displacement reactions

Colegio Católico Notre Dame Caguas, P.R Laboratory: Titration of an Acid with a Base Tristian Pérez Rivera 12-136 AP Chemistry Professor Judith Martínez PhD Objective * The purpose of this laboratory is to recreate and understand what titration is. Hypothesis * If the experiment works correctly, we should determine the amount of a substance by adding a carefully measured volume of a solution with known concentration until the reaction of both is complete. Materials * Computer Pre-lab

A mixture of the essential oils, eugenol and acetyleugenol, will be steam distilled from cloves. These compounds are isolated from aqueous distillate by extraction into dichloromethane. The dichloromethane solution is shaken with aqueous sodium hydroxide, which will react with eugenol, to yield the sodium salt of eugenol in the basic aqueous layer, and acetyleugenol in the organic layer. The basic aqueous layer can be acidified to re-extract eugenol from it. And the organic layer can be dried and

Our group was interested in this Chemical because it is a very common, readily used household cleaning agent. Originally we chose Clorox bleach because it is commonly referred to as highly toxic and lethal. We wanted to know more about its chemical makeup to better understand the dangers that come while using Clorox bleach. History: The active ingredient in household bleach is Sodium hypochlorite, and it was discovered by the French chemist Berthollet, in Javel on the outside of Paris, in 1787

determined. The cement specimens were examined under microscope All concrete blocks were placed in separate plastic bags .The sufficient sulphuric acid solution was added to the bags with 2 specimens (mortar mix and pea gravel).The sufficient sodium hydroxide solution was added to the other bags with 2specimens (mortar mix and pea gravel) and water was added to the bags with final 2 mortar mix and pea gravel specimens. All plastic bags were sealed and the mass of each block has been determined again,
