What is most likely the pH of a solution containing many hydroxide ions (OH-) and few hydrogen ions(H+)

In a scientific experiment, the dependent variable is the condition that is being tested and measured. The independent variable is the condition that is being changed or controlled. In this example, the amount of salt is varied, and the boiling point of water is measured. Therefore, the independent variable is the amount of salt, and the dependent variable is the temperature at which the water bolls.

A solid turns into a liquid by melting, and a liquid turns into gas by vaporization.

A hypothesis is the use of prior knowledge in order to provide a hypothetical explanation for why something may or may not occur. A hypothesis can be proved wrong or right based on the results of the experiment and repeated trials.

Homeostatic mechanisms are involuntary actions by organs, glands, tissues and cells to maintain balance within the body. If a function is disrupted the body will readjust in an attempt to maintain balance. During periods of starvation the body will break down glucose reserves in order to maintain normal glucose levels.

Enzymes act as catalysts for biochemical reactions. A catalyst is not consumed in a reaction, but rather lowers the activation energy for that reaction. The potential energy of the substrate and the product remain the same, but the activation energy-the energy needed to make the reaction progress can be lowered with the help of an enzyme.

The uterus has three layers. The inner layer is called the endometrium. The middle layer is called the myometrium. The outer layer of the uterus is called the serosa or perimetrium.

In general, atomic radius increases moving down a group due to the increasing number of electron shells. In general, atomic radius decreases moving from left to right across a period due to the increasing number of protons in the energy level. Therefore, atoms of elements in the bottom-left corner of the periodic table tend to have the largest atomic radii.

A scientific argument should be based on measurable and observable facts such as the patient's current symptoms and health history. Discussing the patient's appearance or the doctor's feelings does not communicate a scientific argument. While insurance may be a factor in most healthcare systems, the status of the patient's Insurance does not communicate a scientific argument that justifies the need for the test

A solution that contains more hydroxide ions than hydrogen ions is a base, and bases have a pH greater than 7, so the only possible answer is choice D. 9.
