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. The magnesium displaces

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

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

Introduction 1.1 Background Information Acids are separated into different categories. These categories are strong acids and weak acids. Hydrochloric and Sulphuric acid are strong acids‚ and Phosphoric acid is a weak acid. When an acid is placed into water‚ it ionises (Tinnesand‚ n.d.). Ionisation occurs when the acid splits up into its two base components. So when Hydrochloric acid is placed into water‚ it splits into a hydrogen ion and a chlorine ion. The amount that an acid ionises depends on its strength

Introduction In this chemical reaction‚ the magnesium will dissolve in the hydrochloric acid to produce hydrogen gas. This is because magnesium is higher than hydrogen in the reactivity series. Therefore‚ when the two reactants are combined‚ a displacement reaction occus and the magnesium displaces the hydrogen‚ forming magnesium chloride and hydrogen gas. Mg (s) + 2HCl (aq) -> MgCl 2 (aq) + H 2 (g) Magnesium + Hydrochloric acid -> Magnesium Chloride + Hydrogen Aim

This experiment is to show how much carbon dioxide is produced during the reaction between an acid (hydrochloric acid) and marble. Equipment: Hydrochloric Acid (20ml) - 0.5M‚ 1M‚ 2M Marble Chips (2g per test) Large Measuring Cylinder Plastic Bowl (3/4 full of water) Rubber Tubing Glass Conical Flask Stopwatch Method The first thing that we did was fill the plastic bowl with water. We only filled it up 3/4 of the way because otherwise the water displaced into

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

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)

syringe. 3. About 3 cm of magnesium ribbon was measured out using a ruler. 4. The magnesium ribbon was polished using steel wool to remove any coating of oxides as magnesium can be a reactive metal. When magnesium is exposed to oxygen it reacts to form metal oxides. This step is necessary in order to obtain reliable results. 5. The mass of magnesium ribbon was measured and recorded using top pan balance. 6. Step 3‚ 4 and 5 was repeated four times. 7. 3M of hydrochloric acid was diluted into 30 mL
