In chemistry, the pH of a solution is defined by the equation pH=-log(H) where H represents the concentration of hydrogen ions in the solution. Any solution with a pH less than 7 is considered acidic and any solution with a pH greater than 7 is considered basic. Fill in the table below. Round your pH's to the nearest tenth of a unit. Concentration Basic or Acidic? Substance pH of Hydrogen Milk 1.6x10 Coffee 1.3x10 Bleach 2.5x10-3 Lemon Juice 7.9×10 Rain 1.6×10

Average

In mathematics, everyone must have heard the term average in one place or other. Almost all types of calculation require taking out an average. In everyday life, the term is used for denoting a certain amount that can be said to be a typical quantity for multiple people or objects. In other words, if a group of people possesses a certain object, then the average gives us an idea regarding the quantity of the object possessed by each person. However, this is solely based on mathematical calculation. It is important to note that most people will not strictly have the average value in a group.
