If a titration of an unknown sample of humic acid required 3.68 mmols of NaOH, how many mmols of humic acid were present in the unknown sample?
States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
To increase the acidity of soil, you can add peat, which contains a complex acid mixture known as humic acid, a diprotic acid (two acidic protons). The complexity of the humic acid makes it difficult to determine how acidic you are making the soil. You decide to use a titration to get a better measure.
