Vigorous pouring from a height is essential to dissolve dioxygen from the air into the solution. Nearly every liquid is either acidic or basic in nature.Acids are molecules that release hydrogen ions (H+) when dissolved in water.Bases release hydroxide ions (OH-).The pH scale is a way of measuring and precisely specifying how acidic or basic a solution is. What To Do: Pour enough milk in the dinner plate to completely cover the bottom to the depth of about 1/4". Find a clean cotton swab for the next part of the experiment.
