A solution of an unknown acid was prepared by dissolving 4.168 g of the solid acid in enough DI water to make 500.0 mL of solution. It takes 23.47 mL of 0.1678 M NaOH solution to neutralize 10.00 mL of the unknown acid solution. Assuming that the acid is monoprotic. What is the concentration of the acid? What is the molar mass of the acid? (Hint: first calculate the total moles in the 500.0 mL flask. The full 500.0 mL of solution was NOT titrated.)
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.
