Lareina the laboratory technician is given the task of making a solution containing HOBr ( Ka = 2.8 x 10 ⁹) and KOBr and testing its behavior when strong acid or base is added to it. Part 1 First, Lareina combines 82.86 g KOBr and 250 mL of 1.50 M HOBr, and adds enough distilled water to make 925 mL of solution. What is the pH of this solution? pH solution= Part 2 Next, Lareina adds 16.0 mL of 2.20 M HNO3 to 350 mL of the solution made in Part 1. What is the pH of the solution after the HNO, is added? pH after HNO, added = Part 3 Finally, Lareina 16.0 mL of 2.00 M NaOH ito 395 mL of the solution made in Part 1. What is the pH of the solution after the NaOH is added? pH after NaOH added =
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.
