Hydroxide (NaOH) by titrating it with Hydrochloric Acid (HCl) and to identify any possible sources of error. A colour change from pink to yellow signified the end of each individual titre as the NaOH had been neutralised. Experimental: Method: Firstly two solutions were prepared to show the colour of the Phenol Red indicator in acid and alkaline conditions. These colours were then used to determine the end point of each titre. In the experiment 0.100M HCl (acid) was added‚ from a burette‚ to a solution

TABLET FRIABILITY METHOD 1. 10 tablets of mefenamic acid was selected and weighed. 2. All tablets was placed into the drum of the tablet abration and friability tester. The rate of rotation was set up at 25 rpm for 10 minutes. Then‚ operation was started. 3. At the end of the operation‚ all tablets was removed. The tablets was cleaned from dust using brush and reweighed again. The percentages loss of weight was determined. RESULT Initial weight of tablets = 5.8315g After operation =

Aim: The aim of my experiment is to find out the rate of reaction between Hydrochloric acid (HCL) and Magnesium (Mg) in different temperatures. The products that will be formed are Magnesium Chloride (MgCl2) and Hydrogen (H2). Prediction: I predict that as the temperature increases the rate of reaction also increases. To further explore the fact I further predict that the rate of reaction will double for every 10° C rise in temperature. I further predict as the temperature rises by 10° C the rate

Some metals react with acids while others do not. In this experiment‚ students will perform 2 reactions: aluminum/zinc with excess 6M hydrochloric acid and aluminum-zinc alloy with excess 6M hydrochloric acid. The purpose of this experiment is to determine the atomic mass of each metal and the percent composition of a known mass aluminum-zinc alloy by determining the moles of H2 gas formed. Zn(s) + 2HCl(aq) → ZnCl2(aq) + H2(g) 1 mole of H2(g) is produced for every 1 mole of Zn(s) 2. 2Al(s)

Aim It is to tell how the reaction between magnesium and hydrochloric acid will be effected if we change the concentration of hydrochloric acid. Introduction In the experiment the magnesium reacts with the hydrochloric acid to create magnesium chloride and hydrogen. The balanced formula for this is: Mg(s) + 2HCL(aq) MgCl2(aq) + H2(g) Magnesium + hydrochloric acid Magnesium Chloride + Hydrogen Magnesium will react with hydrochloric acid‚ because it is higher in the reactivity series than hydrogen

Should fluorine be added to water? Introduction: Fluoride is a natural mineral and a chemical‚ which is a compound of fluorine that is the most commonly used in water sources. However not only for that‚ it also has a various number of other uses in example: making molten metals flow‚ and burning materials etc. as it is an extremely reactive and highly toxic element‚ so when it comes to adding fluoride to public water‚ that’s when mankind is faced with some extremely

Title: Measuring the loss in mass of Marble chips and Hydrochloric acid Aim: We will measure the loss in mass of the marble chips (CaCO 3 ) as it reacts with Hydrochloric acid (HCl). This one method of measuring the rate of reaction. We will use a balance to measure this mass loss as the reactants are used up to form product. Safety: * As Hydrochloric acid is corrosive wear a lab coat‚ gloves and safety goggles. * Take care when using the glassware not to cut yourself. * When

Introduction We are going to do an experiment to see how surface area effects the rate of reaction when added to hydrochloric acid. I will add calcium carbonate (marble chips) to hydrochloric acid. When calcium carbonate is added to hydrochloric acid a reaction takes place. The solution fizzes and gives off the gas carbon dioxide. I will collect this gas in a gas syringe and will time how long it takes for the reaction to produce 100cm3 of carbon dioxide. CaCO3 +2HCL Co2 +CaCl2 +H2O CalciumHydrochloricCarbonCalciumWater

Aim During this experiment I will be investigating if heating limestone and changing the concentration of the acid will affect the rate of reaction. Preliminary work Before doing our main experiment‚ we will have to conduct another experiment‚ to see what concentration of acid we will have to use. We done this using 0.1M‚ 0.5M and 1M of Hydrochloric acid‚ and 0.1g of powdered limestone‚ we used powdered limestone‚ as it would be a fairer test‚ I think this as all the particles of limestone will
