the rate of reaction between Calcium Carbonate and Hydrochloric Acid. Just from looking at the aim of the investigation I already know that a salt would be formed because a carbonate with an acid forms a salt. In this investigation the substance that is formed is Calcium Chloride‚ Water and Carbon Dioxide. The symbol equation for this is: CaCo3  Ca2+ + Co32- Hcl  H+ + Cl- Add these all together to get CaCO3(s) + 2H+(aq) --> Ca++(aq) + H2O + CO2(g) The rate of reaction is just the

Experiment on Metals Aim-To find out which of these metals will be most reactive with hydrochloric acid‚and plan an investigation to test it out.The Metals given:Calcium‚Aluminium‚Iron‚Magnesium and Zinc. Prediction-I predict that the metal will be the most reactive with hydrocholoric acid is calcium because calcium is in Group 2 which is the alkaline earth metals in the periodic table and because calcium is at the extreme left side of the periodic table and as you go across a period‚the element

using different concentrations of hydrochloric acids (HCl) and indigestion relief tablet. I will also mention the time which was taken in the experiment‚ to see how fast the hydrochloric acid took with indigestion tablet with different concentrations. Indigestion tablets are alkali and they are used for to neutralise the excess acid in the stomach. Indigestion Tablet Indigestion is caused by excess acid in the stomach. The tablets neutralise some of this Acid and this is known as ‘Neutralization’

Chemical Reactions- Sodium Hydroxide A chemical reaction is a change where two or more substances are changed into a new substance. You can identify a chemical reaction by colour change‚ effervescence (bubbles)‚ when light or heat given off‚ and the change is usually irreversible. There are 6 main types of chemical reactions- combustion (often called burning)‚ synthesis‚ decomposition‚ neutralization‚ single replacement and double replacement. A combustion reaction is a reaction with oxygen‚ and

A neutralization reaction of ethanoic acid and sodium hydrogen carbonate Cristina Li 17th April 2017 Introduction The hypothesis is the balloon will be bigger and bigger with the increase of vinegar. The chemical reaction between the baking soda and vinegar produces bubbles of carbon dioxide gas as part of this acid-base reaction. Sodium hydrogen carbonate (baking

An Investigation into the Factors Affecting the Rate of the Reaction between Calcium Carbonate and Hydrochloric Acid A chemical reaction is the process by which atoms or groups of atoms are redistributed‚ resulting in a change in the molecular composition of substances. The reaction rate is how quickly a reaction occurs and this can be affected by four different factors: ¡¤ changing the surface area of any solids involved ¡¤ changing the concentration of reactants in solution ¡¤ changing the temperature

of acid by titration with sodium hydroxide Ms. Hoang November 2012 Introduction: The purpose of this experiment is to demonstrate an example of how to determine the unknown molarity of hydrochloric acid by titration with a base (sodium hydroxide). Titration is a common laboratory method of quantitative chemical analysis that is used to determine the unknown concentration of an identified analyte (wekipedia). The first step will be measuring and combining water and acid (Hydrochloric acid)

____________________________________________________________ ____________________________________________________________ ____________________________________________________________ ______ This lab was basically about finding the percentage of acetylsalicylic acid in an aspirin tablet. First‚ the base was created‚ which was made out of 1.00 g of NaOH and D-water. Then the buret was attached to the clamp on the ring stand and the base was poured into the buret. After that‚ one by one‚ an aspirin tablet was dropped

Hypothesis: The higher the concentration of hydrochloric acid‚ the faster the reaction will take place because there will be more hydrochloric acid particles to collide with the marble chip particles therefore resulting in a quicker reaction. The lower the concentration‚ the weaker the reaction will be as there will be fewer particles so less chance of a collision and a lower rate of reaction. Equipment: Conical flask – to hold the hydrochloric acid and marble chips Boiling tube – to hold and

An 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
