In this I/GCSE Chemistry blog post, we will be looking at different types of nitrates!

NITRATES

These first melt, and then break down into the nitrite, releasing oxygen (which can be tested for with a glowing splint).

MOST OTHER METAL NITRATES

• These give off oxygen and brown fumes of nitrogen dioxide, e.g.

AMMONIUM

• This decomposes completely. 

FERTILISERS

In I/GCSE Chemistry, we need to know why and how fertilisers are useful.

• The three major nutrients are nitrogen, phosphorus and potassium – N, P and K. They are sold using a three-number 

NPK system:

• Adding excessive quantities of fertiliser will not continue to improve yield. There is a point beyond which the crop will no longer respond.  
• The catalyst used to assist in the reaction of ammonia to form NO is platimum. 
• The fertiliser ammonium nitrate is manufactured by the neutralisation of nitric acid with ammonia.
• Ammona gas is formed when an ammonium ion is reacted with sodium hydroxide solution. 

That is all for this post!
