What would be the concentration of X 2- if a 10 mL of a 1 M solution of KOH was added to 50 mL of a 0.11 M of H2X. Write out the two neutralization reactions with KOH, H2X, and HX - . Assume the neutralization happens in two separate steps. Ka1 = strong and Ka2 = 1.0x10-5 . A) Write the two neutralization reactions with KOH with H2X. B) Determine the moles of H2X after the first neutralization. C) Determine the pH of the 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.
