What is the measure of acidity in terms of hydronium ion concentration?
Recycledbirdhouses
pH is a measure of the activity of hydroxide (OH-) and hydronium (H3O+) in aqueous solution. Acidic solutions have greater numbers of reactive hydronium ions. Basic solutions have more hydroxide ions and less reactive hydronium ions.

∙ 15y agothe pH of a substance is a logarithmic function of the concentration of the number of free hydrogen atoms (or hydronium ions) in solution.
pH = -log [H+]
So, yes. That statement in your question is correct.

∙ 14y agoAs hydrogen ion concentration increases, acidity increases. A Base is a solution that attaches to hydrogen ions and effectively "diffuses them", so a lack of base will make for a solution with a high hydrogen ion concentration. Acidity is measured in pH, or percent hydrogen. The higher the pH, the more hydrogen ions, and thus the more acidic.

The terms base and alkaline refer to solutions that hydronium hydroxide hydrogen?
hydroxide anion, OH-: alkaline solution hydrogen cation, H+; hydronium cation, (H3O)+: acidic solution
Is oxygen a base?
No. Oxygen is an element and, in terms of acidity and alkalinity is neutral.
Is the measure of the amount of dissolved salts in seawater expressed as grams of salt per kilogram of water?
That would be one way of doing it. Chemists normally measure concentration of a solute in terms of moles per liter.
What is the pH of sweet crude oil?
You cannot measure the pH of crude oil since by definition pH is the negative log of the hydrogen ion concentration. In order for hydrogen ions to exist, some amount of water must exist for the ions to dissociate into. Acidity is generally given in terms of milligrams of potassium hydroxide required to neutralize the oil per gram of oil (mg KOH/g).
What does a change in pH of one unit represent in terms of hydrogen ion concentration?
-1 pH unit = *10 concentration
Describe the function of the pH scale?
It is a measure of the concentration of hydronium (H30+11OH) ionic bonds in a solution. The greater the concentration of hydronium ions, the lower the pH and the more acidic it is. Solutions with a pH of less than two are considered strong acids. Solutions with a pH of greater than 12 are considered strong bases.
What is the pH system and the terms utilized to identify product?
The pH measure the acidity or basicity of a solution; the range is 1-14. Acidity is under pH=7, basicity is over pH=7, pH=7 is neutral.
The terms base and alkaline refer to solutions that hydronium hydroxide hydrogen?
hydroxide anion, OH-: alkaline solution hydrogen cation, H+; hydronium cation, (H3O)+: acidic solution
Is oxygen a base?
No. Oxygen is an element and, in terms of acidity and alkalinity is neutral.
What is acidity and alkalinity?
Acidity and alkalinity are terms used to describe the concentration of hydrogen ion (H+) in a solution. It is measured with the pH scale, a set of values usually given as 1 to 14 where 1 is very acidic, 7 in neutral, and 14 is very alkaline. The numbers are the negative log of the H+ ion's mole concentration. pH is measured with a pH meter or various indicator solutions which change colour at different pH levels.
What are PH indicators used for?
it tests how acid or alkaline a substance is, and can have many uses, from science, to gardening. It measures on the pH scale, which goes from 1-14 and comes in different forms, from electronic testers with digital readouts, to a strip of paper which changes color when dipped in a liquid
Is the measure of the amount of dissolved salts in seawater expressed as grams of salt per kilogram of water?

What does the pH scale monitor?
Acidity. Or in chemical terms, the concentration of hydrogen ions versus hydroxide ions. Greater [H+] means a lower pH. Greater [OH-] means higher pH. [H+]*{OH-] will always equal 10^-14.
The first person to define an acid and base in chemical terms was?
The first person to categorize acids and bases in chemical terms would be Danish chemist, Soren Peder Lauritz Sorensen, and he did so in 1909. Sorensen was first to introduce the concept of pH, the scale of measure for acidity and basicity.

What does a pH probe measure?
a PH probe measures the concentration of Hydrogen ions in a solution in moles per litre. In less scientific terms it measures how acidic or basic a solution is.
Are diet sodas any better to drink than regular soda in terms acidity level?
No.
