What happens if magnesium is added to hydrochloric acid

Add water to the bucket at a ratio of 1 part baking soda to 10 parts water. In the neutralization of hydrochloric acid by sodium hydroxide, the mole ratio of acid to base is Hydrochloric acid reacts with sodium hydroxide to form sodium chloride the salt and water. Hydrogen bromide reacts with potassium hydroxide to form potassium bromide the salt and water. You would get salt water and lots and lots of heat.

So if that funnel were long enough to thoroughly mix the two, and allow them to cool off, yes, you could drink them. You would not need to cool them off. Mercury metal. When zinc reacts with hydrochloric acid, the reaction bubbles vigorously as hydrogen gas is produced.

When you are ready, add a 3 cm strip of magnesium ribbon to the flask, put the bung back into the flask as quickly as you can, and start the stopwatch. Record the volume of hydrogen gas given off at suitable intervals eg 10 seconds. Continue timing until no more gas appears to be given off.

Use Practical experiments. Category Practical skills and safety Investigation Acids and bases Physical chemistry Reactions and synthesis Metals Rates of reaction. Consider chemical reactions in terms of energy, using the terms exothermic, endothermic and activation energy, and use simple energy profile diagrams to illustrate energy changes.

Systems and interactions 7. Investigate the effect of a number of variables on the rate of chemical reactions including the production of common gases and biochemical reactions. Building blocks 2. Develop and use models to describe the nature of matter; demonstrate how they provide a simple way to to account for the conservation of mass, changes of state, physical change, chemical change, mixtures, and their separation. Leaving Certificate Chemistry 6. Rates of reaction 6.

Draw, and interpret, graphs showing the quantity of product formed or quantity of reactant used up against time. Draw tangents to the curves on these graphs and use the slope of the tangent as a measure of the rate of reaction. HT Calculate the gradient of a tangent to the curve on these graphs as a measure of rate of reaction at a specific time.

The experiment is carried out in the same way, but:. Evaluate the hazards and the precautions needed to reduce the risk of harm. For example:. Practical - effect of changing the conditions on the rate of reaction Investigate the effects of changing the conditions of a reaction on the rates of chemical reactions by measuring the production of a gas.

Aims To investigate the effect of changing the conditions on the rate of a reaction. Changing the concentration of acid Method Support a gas syringe with a stand, boss and clamp. Using a measuring cylinder, add 50 cm 3 of dilute hydrochloric acid to a conical flask.

Add a 3 cm piece of magnesium ribbon to the flask. That said, using the plastic cup calorimeter is a good substitute for a real calorimeter in classroom laboratory experiment because it still acts as an insulator to keep the heat inside and makes a better calorimeter than other materials because of its high specific heat.

Hypothesis: I predict that the higher the volume of concentrated Hydrochloric Acid the less time it will take for the cross to disappear. This experiment has to do with the Collision theory. But collisions with too little energy do not produce a reaction. The particles.

The rate of reaction: amount of reactant used up for each unit of time. Prediction: I predict that as the concentration of the hydrochloric acid decreases the rate of reaction decreases. I think this because the more the acid the faster the reaction goes as the acid is stronger, which causes more pressure.

Pressure increases as there are more collisions within the container, with the particles. Some collisions are successful and give a product while others don't because particles don't have enough energy.

Activation energy - The amount of energy needed for the reaction to be started. If there is enough energy then the reaction takes place and a product is formed, but if there isn't enough then no reaction takes place.

There are two possibilities for increasing the rate of reaction: 1. The activation energy is reduced so that there is a better chance of particles having enough energy to react.

My results are reliable enough to support my conclusion as I had concluded that increasing the concentration of HCl would lead to a decrease in the time taken to react. My results show this because the correlation is positive meaning that it would take longer for a solution to react by decreasing the concentration of HCl.
