The two of the four quantum numbers that determine the energy level of an orbital in a multi-electron atom needs to be determined. Concept introduction: An atom consists of three sub-atomic particles; electrons, protons and neutrons. The Bohr’s model purposed the concept of energy levels around the nucleus. It was first most accepted atomic model. The quantum mechanical model is based on certain concepts like quantum numbers, Heisenberg uncertainty principle, etc. Quantum numbers are used to indicate the position and energy of an electron in an atom at a certain energy level. Electrons in an atom are always placed in certain energy levels called orbitals. The position, energy and spin of electrons are explained with the help of four quantum numbers.

A small artisanal cheesemaker is testing the acidity of their milk
before it coagulates. During fermentation, bacteria produce lactic
acid (K₁ = 1.4 x 104), a weak acid that helps to curdle the milk and
develop flavor. The cheesemaker has measured that the developing
mixture contains lactic acid at an initial concentration of 0.025 M.
Your task is to calculate the pH of this mixture and determine whether
it meets the required acidity for proper cheese development. To
achieve the best flavor, texture and reduce/control microbial growth,
the pH range needs to be between pH 4.6 and 5.0.
Assumptions:
Lactic acid is a monoprotic acid

For simplicity, you can use the generic formula HA to represent the acid
You can assume lactic acid dissociation is in water as milk is mostly water.
Temperature is 25°C
1. Write the K, expression for the dissociation of lactic acid in the space provided. Do not forget to
include state symbols.…
