Option A. Hydrogen Ions
The dissolution of carbon dioxide in the oceans produce hydrogen ions as when carbon dioxide is dissolved in the ocean it leads to Ocean Acidification. This Acidification produces the hydronium ions as more acidic nature implies higher concentrations of hydrogen ions.
Carbon dioxide is a gas that readily dissolves in water to give Carbonic Acid , bicarbonate ions and carbonate ions , all of which are acidic in nature. This lowers the pH of the ocean making the waters more acidic. Therefore the acidity of oceans is largely dependent on carbon compounds and the amount of Carbon dioxide.
The reaction of Carbon dioxide with water to give carbonic acid :
CO2 + H2O → H2CO3

Iron is constantly working to support life on Earth, from supplying plants with nutrients to serving as a key component of steel to carrying oxygen in your blood.
- Iron is the most common metal, its pure form corrodes quickly when exposed to humid air and high temperatures.
- it is abundant in the sun and stars.
- It contributes to the synthesis of chlorophyll in plants.
- It is a part of hemoglobin, a blood protein that transports oxygen from the lungs to the body's tissues in mammals.
- The majority of it is used to create steel, an iron and carbon alloy used in manufacturing.
- There are four main structural forms of iron, known as allotropic forms, in which atoms are bound in various ways.
These are few properties of iron that are unusual for metal.

Answer: The pH of the substance is 8.25. The solution is basic.
Explanation:
pH or pOH is the measure of acidity or alkalinity of a solution.
pH is calculated by taking negative logarithm of hydronium ion concentration. The acids have pH ranging from 1 to 6.9 , salts have pH of 7 and bases have pH ranging from 7.1 to 14.
Putting in the values:
Thus as pH is more than 7, the solution is basic.
The pH of the substance is 8.25. The solution is basic.
