What is ph
pH measures the acidity or basicity of a solution. It stands for “power of hydrogen” and is a scale that ranges from 0 to 14, with 7 being neutral
What is the 10 fold rule
for each unit increase in pH, there is a 10 fold increase in the hydrogen ion concentration
Neutrlization reaction
A neutralization reaction is a type of chemical reaction between an acid and a base
what are the reactants and products
The substances that go into a chemical reaction are called the reactants, and the substances produced at the end of the reaction are known as the products.
What ways do we measure acidity
litmus paper, pH paper, cabbage juice, phenol red
What is nitrogen fixation
a chemical process that converts atmospheric nitrogen into ammonia, which is absorbed by organisms
How does nitrogen fixation occur
fossil fuels, industrial processes
Organic elements
organic compounds are compounds that include carbon atoms(ex.Carbohydrates
Lipids,Proteins and amino acids,Nucleic acids).
inorganic elements
do not contain carbon atoms
Fertiliser 3 chemicals and ratio
10 percent nitrogen, 15 percent phosphorus, and 10 percent potassium.
