Why does Hydrochloric Acid dissolve magnesium? As mentioned, hydrochloric acid is a strongly ionizing non-oxidizing acid, and magnesium is a very active metal. The HCl 'lets' the magnesium surrender two electrons to the hydrogen, allowing the hydrogen to escape as hydrogen gas, and the magnesium to combine with the chlorine.
Please forgive any resultant repetition or failures of chronological order.
Hi, I was wondering if you could help me, I've got to do my GCSE chemistry coursework on the reaction between hydrochloric acid and magnesium ribbon, but I can't find any Scientific Knowledge to put in the coursework, would you please be able to give me some?
Thank you very much, Laura [last name deleted for privacy by Editor] - Lincoln A. Hi, yeh the magnesium ribbon reacts with the hydrochloric acid in a redox reaction, where the magnesium is reduced and hydrogen is oxidised as it gains electrons from the magnesium.
It becomes MgCl which is soluble in solution so effervescence is seen as it dissolves and hydrogen is released. Background knowledge you should just write about different factors affecting rate like surface area, concentration or temperature depending on which one you are looking at and explain why, for example with temperature talk about the kinetic energy and collision theory.
I think Kate is wrong: You are right, the magnesium is oxidized and the hydrogen is reduced.
Additional good discussions on this topic can be found on threads and One typical reaction to explore at secondary level is the rate of the reaction between magnesium ribbon and hydrochloric acid.
The instructions on a worksheet may state ‘time how long it takes for the magnesium to disappear’. - The Effect of Temperature of Hydrochloric Acid on the Rate of Reaction Between Hydrochloric Acid and Magnesium Aim To investigate if the temperature of hydrochloric acid will affect the rate of reaction between hydrochloric acid and magnesium.
Chemistry Rates of Reaction Coursework: Sodium thiosulphate and hydrochloric acid Simple Procedure Place a conical flask on a piece of paper with a cross on it. Add hydrochloric acid and sodium thiosulphate, and record the amount of time taken for the cross .
Rate of reaction The Effect of concentration on the reaction between magnesium and hydrochloric acid. Mg(s) + 2HCl(aq) MgCl2(aq) + H2(g) Aim: In this experiment I am going observe and record the reaction between magnesium and different concentrations of hydrochloric acid/5(2).
I am going to investigate how the rate of the reaction between sodium thiosulphate and hydrochloric acid depends on the concentration of sodium thiosulphate.
The reaction rate of a chemical reaction is the speed of production of products from reactants. Chemistry Rates of Reaction Coursework: Sodium Thiosulphate and Hydrochloric Acid.
