A student is asked to standardize a solution of sodium hydroxide. He weighs out 0.963 g potassium hydrogen phthalate (KHCaH4O4, treat this as a monoprotic acid). It requires 19,9 mL of sodium hydroxide to reach the endpoint. A. What is the molarity of the sodium hydroxide solution? M This sodium hydroxide solution is then used to titrate an unknown solution of hydroiodic acid. B. If 11.9 mL of the sodium hydroxide solution is required to neutralize 27.0 mL of hydroiodic acid, what is the molarity of the hydroiodic acid solution?
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.
