What do we use ammonia for in chemistry?

i am looking for good websites which give properties and equations, etc about nitrites, nitrates and ammonia. Also, possible a website which has info about how to solve (change) levels of nitrites, nitrates and ammonia. Thankyou... please make sure it...

I typically use a very diluted bleach/water (food safe grade) mix around the house for disinfectant. Sometimes I'll maybe dump a cup in the toliet or in with the wash but no more than once a week. Lately I've been hearing great things about ammonia for...

Heloise says to wash my towels and wash cloths in non-sidsing ammonia to remove odors and stiffness. I have 2 questions: 1. How do I tell if the ammonia I bought is non-sudsing? It doesn't say on the label, and I can't find any that does. 2. Is it safe...

Ammonia is added to a precipitate. Since ammonia is a base and NaOH is a base, can NaOH solution be substituted for the NH3 solution? Why?

How can i calculate the maximum mass of ammonia that can be produced from 1000g of nitrogen? Here is the equation for making ammonia: (The reaction is reversible) N2 + 3H2 ...show more

I do not know any chemistry at all, but I am quite fluent in mathematics.  Could you explain how to do this calculation when I don't know what the concentration of the ammonia solution I am using?

I am going to do a partial water change because the nitrite levels are a bit high, and i suspect the ammonia levels may be a bit high as well. Can I use ammonia pellets/tablets safely with my turtle? He is a red ear slider.
