To investigate how does the concentration of Hydrochloric acid affect the rate of reaction? Outline I aim to discover how different concentrations of Hydrochloric acid influence the rates of reaction. In order to carry out this investigation I have decided to use marble chips‚ which I will vary the sizes as powder‚ small chips and large chips. I will also be changing the concentration‚ the different concentrations are as follows 0.2m‚ 0.5m‚ 1m‚ 1.5‚ 2m. I have chosen these concentrations as they

investigation in to the rate of reaction Plan: I am going to investigate the rate of reaction. The reaction I will be using is: Calcium Carbonate + Hydrochloric acid ---- Calcium Chloride + water + carbon dioxide. CaCO3 + 2HCl ---- CaCl +H2O + CO2 Measurements and Variables: The variables I have chosen to change is strength of the hydrochloric acid which will be 1 mole‚ 0.7 mole‚ 0.5 mole‚ 0.3 mole and 0.1 mole some variable I will not be using are temperature‚ mass‚ density. The measurements
Premium Chemical reaction Reaction rate Chemistry
Hypothesis: In a reaction between calcium carbonate and hydrochloric acid‚ the products calcium chloride‚ carbon dioxide and water are formed. I predict that the higher temperature of HCl acid‚ the higher the reaction rate will be‚ this is because at a higher temperature there will more fast-moving hydrochloric acid molecules per set volume. This means that there will be a higher chance of the calcium carbonate molecules colliding with the hydrochloric acid and reacting‚ with enough energy to break the activation

Experiment 7 INVESTIGATING STOICHIOMETRY WITH SODIUM SALTS OF CARBONIC ACID Introduction In this experiment we are going to get a better understanding of chemical stoichiometry. We are going to be reacting sodium bicarbonate (NaHCO3) and sodium carbonate (Na2CO3) with hydrochloric acid (HCl). To start off the mass of two unknown substances (being the sodium bicarbonate and sodium carbonate) will be taken. We will need to construct balanced equations for both of the reactants with the HCl and

Investigating How Concentration of Acid Affects the Reaction Between Calcium Carbonate and Hydrochloric Acid Introduction ============ According to the collision theory temperature‚ concentration‚ surface area and catalysts all affect rates of reaction as shown in the diagrams below. Increasing any of these should increase the number of collisions and so increase the reaction rate up to an optimum point. Increasing the temperature causes the particles to collide with more

eLearning 2009 Publication No. 91860 Rate of Reaction of Sodium Thiosulfate and Hydrochloric Acid Rate Laws Introduction The purpose of this demonstration is to investigate the effect of sodium thiosulfate concentration on the rate of reaction of sodium thiosulfate with hydrochloric acid. The reaction‚ which produces solid sulfur‚ will be followed by measuring the time needed for the reaction mixture to become opaque. The results will be analyzed graphically to determine the order of

2. An aqueous solution of KCl is colorless‚ KMnO4 is purple‚ and K2Cr2O7 is orange. What color would you expect of an aqueous solution of Na2Cr2O7? Explain. Orange. 3. Explain why hexane will dissolve benzene but will not dissolve sodium chloride. Sodium chloride is an ionic compound. 4. Some drinks like tea are consumed hot or cold‚ whereas others like Coca-Cola are consumed only cold. Why? For taste reasons‚ these drinks can be drunk if the user likes It but having coca cola like tea

Gracen Seiler April 7th‚ 2015 Section- 109 Investigating Stoichiometry with Sodium Salts of Carbonic Acid Introduction- This experiment is intended to help find a better understanding of chemical stoichiometry through titrations of NaHCO3 and NA2CO3 with HCl. A chemical reaction is a process that involves rearrangement of the molecular or ionic structure of a substance‚ as opposed to a change in physical form in a nuclear reaction. Titration is when a measured amount of
