<h3>
Answer:</h3>
A. It is a very strong base.
<h3>
Explanation:</h3>
To answer the question we need to ask ourselves several questions
What is pH?
- pH refers to the measure of alkalinity or acidity of a substance.
How is pH measured?
- pH is measured by determining the concentration of Hydrogen ions (H⁺) in a given solution.
- Then calculated by getting negative logarithm of hydrogen ions concentration.
- That is, pH = -log[H⁺]
What does pH tell about a solution?
- A solution with a pH below 7 is acidic while a solution with a pH above 7 is basic while that with a pH of 7 is neutral.
- A pH of 1 to 3 represents a strong acid while a pH of 4 to 6 represents a weak acid.
- Strong alkali or bases have a pH of 12 to 14 while weak alkali or bases have a pH of 8 to 11.
- Therefore, a solution with a pH of 14 is a very strong base
Air is a mixture and table salt is a compound. Air is composed of different types of elements that can be separated whereas table salt is more uniform and consists of Na (sodium) and Cl (chloride) to form the compound sodium chloride.
A beta particle, also called beta ray or beta radiation (symbol β), is a high-energy, high-speed electron or positron emitted by the radioactive decay of an atomic nucleus during the process of beta decay. There are two forms of beta decay, β− decay and β+ decay, which produce electrons and positrons respectively.
Answer:
Clay
Explanation:
Since Clay has a very small particle size it compacts or has a high surface area which slows the path of water, holding it for longer periods compared to other soil components.
