Nuffield A level chemistry Practical A selection of precipitation reactions using Sodium Carbonate (unless otherwise specified). A precipitation reaction is a reaction in which soluble ions in separate solutions are mixed together to form an insoluble compound that settles out of solution as a solid. That insoluble compound is called a precipitate.

The exact chemical reaction involved in the thermite reaction depends on the metals that you used, but you're essentially oxidizing or burning metal

# data[].attributes.body
The thermite reaction has a high ignition temperature, so it takes some serious heat to initiate the reaction.

# data[].attributes.body
The Thermite reaction is a reaction when metal burns. When you perform the thermite reaction on a block of ice it creates an explosion.

This video is showing the rate of reaction that occurs for sodium thiosulphate and hydrochloric acid. The women is showing what happens when you mix the two substances together and how long it takes for the reaction to occur. She uses 5 different beakers to see the difference in time for each.

Rate of Reaction of Sodium Thiosulfate and Hydrochloric Acid

# data[].attributes.body
As the sulfur concentration increases, shorter wavelengths are scattered

and longer ones pass through,

this causes an increase of reddish color to appear on the overhead.

In the beginning, both compounds are clear,

but when mixed together they form a yellow precipitate solid sulphur.

The rate at which the solution turns cloudy demonstrates the speed

at which the two compounds are reacting with each other.

Baking soda and vinegar react with each other because they exchange atoms.

They exchange a proton and in this reaction baking soda acts as the base and takes a proton away from vinegar which is an acid.

The reaction releases gas when the baking soda gains a proton it transforms into water and carbon dioxide.

People can make their own bottle rocket made from baking soda and vinegar.

You can do this by putting baking soda in a rolled up piece of paper and adding vinegar to a empty bottle.

Then you put the two together, cork it, and shake it up to see the rocket go as high as it can.

Baking soda and vinegar react with each other because of an acid base reaction.

Baking soda is a bicarbonate (a salt) and vinegar is an acetic acid (the acid that gives vinegar its characteristic taste.

The pure acid is a colorless viscous liquid or glassy solid).
