Answer:

Atoms are the smallest particle that make up living <u>both</u><u> </u><u>living</u><u> </u><u>and</u><u> </u><u>non</u><u> </u><u>living</u><u> </u> things, they are made up of subatomic particles; protons, neutrons and electrons. Of these the electrons <u>protons</u><u> </u> and neutrons are in the nucleus and the protons <u>e</u><u>l</u><u>e</u><u>c</u><u>t</u><u>r</u><u>o</u><u>n</u><u>s</u><u> </u>orbit around the nucleus. Of the subatomic particles, the electrons have the largest <u>s</u><u>m</u><u>a</u><u>l</u><u>l</u><u>e</u><u>s</u><u>t</u><u> </u>mass and are negatively charged, the neutrons (negative charge) (<u>no charge)</u> and protons (positively charged) both have a relative mass of 1. Atoms contain an equal number of protons and neutrons <u>electrons</u>, so carry no overall charge. An element is a substance made up of only two <u>one</u> type of atom. Elements can be found in the Periodic table of elements, they usually have two numbers next to the chemical symbol, the larger number is generally the atomic <u>mass</u> number, which represents the number of neutrons and the number of protons. The smaller number is the relative atomic mass <u>atomic</u><u> </u><u>number</u> which represents the number of electrons or neutrons <u>protons</u>. In order to calculate the number of neutrons, you minus the atomic number from the relative atomic mass.

A buffer consists of 0.45 M CH3COOH (acetic acid) and 0.35 M CH3COONa. The Ka of acetic acid is 1.8 x 10-5 . a) Calculate the pH
Zigmanuir [339]

Answer:

A) pH of Buffer solution = 4.59

B) pH after 5.0 ml of 2.0 M NaOH have been added to 400 ml of the original    buffer solution = 4.65

Explanation:

This  is the Henderson-Hasselbalch Equation:

 pH = pKa + log\frac{[conjugate base]}{[acid]}

to calculate the pH of the following Buffer solutions.
