Chemistry Coursework Rates of Reaction Investigation Introduction In this investigation I am going to be investigating the reaction between marble chips and hydrochloric acid‚ and to see what differences in the rate of this reaction arise when different concentrations of acid are used. Below is the word equation for this reaction: Calcium Carbonate + Hydrochloric Acid = Calcium Chloride + Carbon Dioxide + Water Below is the fully balanced chemical equation for this reaction. CaCo3 + HCl

of an acid affects the rate of the reaction. I have set up the experiment’s equipment as shown on figure 1. As you can see by figure 1‚ I have used the reaction between sodium thisoulphate solution and hydrochloric acid (HCL) to come up with results that will help me draw conclusions regarding the effects of the concentration of the acid. I decided to use this particular reaction due to the fact that the product of the reaction between sodium thisoulphate and hydrochloric acid (HCL) is precipitates

Melissa Carrithers AP Chemistry 12/17/14 Rate Law Determination Pre-Lab Purpose: The purpose of this lab is to observe the reaction between sodium hydroxide and crystal violet so that the order of the reaction could be determined along with the rate constant‚ k‚ and the half-life for this reaction. Hypothesis: If the reaction between crystal violet and sodium hydroxide reacts appropriately‚ then the order will be first order. Procedure: Mix 10 mL of sodium hydroxide and crystal violet solution together

SODIUM gSodium is a chemical element with the symbol Na (from Latin: natrium) and atomic number 11. It is a soft‚ silver-white‚ highly reactive metal and is a member of the alkali metals; its only stable isotope is 23Na. The free metal does not occur in nature‚ but instead must be prepared from its compounds; it was first isolated by Humphry Davy in 1807 by the electrolysis of sodium hydroxide. Sodium is the sixth most abundant element in the Earth’s crust‚ and exists in numerous minerals such

Lab 3: Reaction Order and Rate Laws Name: Student Lab Partners: None Date of Experiment: 16 March 2014 Location: My House Course Number: CHE112 Abstract: When combining compounds‚ there are always two roles considered in the reaction. These are reactants and products. Reactants are the initial compounds before mixing. The products are synonymous with the term byproduct‚ or what remains when the reaction occurs. For example‚ Sodium (Na+) and Chlorine (Cl-)

Abstract We performed two trials of nine different variables of reactions to determine what increases/decreases reaction rates. The variables we used are hot/cold and room temperature water‚ a equal mixture of HCL and water‚ A equal mixture of NaOH and water‚ either a whole‚ broken‚ or finely crushed Alka-seltzer tablet. The fastest rate average was at 0.04 s (finely crushed Alka-seltzer with room temp. water). The slowest rate average is 8.02 s (Alka-seltzer with cold water). Introduction

Lab Report: How Temperature affects Reaction Rate Aim: The Aim is to investigate how temperature can affect Reaction Rate. The experiment will be performed by heating equally sized and weighted lime stones with equal amounts and concentration of Hydrochloric acid at different temperatures. The temperatures will be 35˚C and 40˚C. We will measure the reaction rates by observing gas release of the reaction between lime stones and Hydrochloric acid. The amount of gas release at different
