What value is ued to express the acidity or bacity of a solution called?
The acidity or basicity are expressed by pH (the negative logarithm of the activity of hydronium ion).
Why do chemists often express the acidity of a solution as a pH value rather than a hydrogen ion concentrated?
it is easier for most people tounderstand a change in pH from 5 to 3, but looking at H+ concentrations of 1 x 10-3 compared to 1 x 10-5 is more difficult for some to grasp.
What is the approximate mass of a neon-11 atom?
The approximate mass is 11. Technically you could express this in units of daltons as 11 Da (Daltons previously called amu, atomic mass unit, or as 11 (the dimensionless, relative atomic mass which chemists simply call atomic weight) .
What is the atomic mass of neon'?

When was Comet Express created?
Comet Express was created in 1995.

What value is used to express the acidity or icity of a solution called?
The acidity and the basicity are expressed by pH (the negative logarithm of the hydronium ion activity).
How do you express total acidity Let's say total acidity of OJ 5 in a 10 ml how do you express that?
with the pH scale
A range of values that are used to express the acidity or alkalinity of a system is?
pH scale...... for acidity it is 0-6.9, neutral is 7.0, Basic is 7.1-14.0
What is the range of values that are used to express the acidity or alkalinity of a system?
The pH scale. The pH scale goes from 0 to 14. Substances that have a pH of 7 are neutral, acids have a pH of less than 7, and bases have a pH of greater than 7.

There are several ways to express the acidity or basicity of a solution Probably the most common means is by using pH How is the numerical value of pH determined and how does its magnitude relate to a?
pH runs on a scale from 0 to 14. The higher the number, the more basic or alkaline a solution is. The lower the number, the more acidic it is. The pH number is a logarithmic scale that relates to the number of free hydrogen or hydroxide ions in solution.
How does a chemical equation express relationships between substances?
The chemical equation is a graphic expression of a chemical reaction.
What are ellagitannins?
According to a website: ellagitannins, a special class of naturally occurring polyphenols which have so far not received the attention they deserve. These polyphenolic substances are found in many plants, including numerous food sources. They not only exhibit unique structural features that fascinate most chemists who are aware of their existence, but also express remarkable biological activities that have yet to attract the interest of the pharmaceutical industry.
What do you have to do to be an artist?
mostly you have to be original with physical substances such as paint or you need to have a significant idea you want to express or if you have both you will probably be a very good artist
What do chemists use the to express the concentration of hydrogen ions in a solution?
[H+]aq square brackets [ ] represent concentration the letter H represents the atomic symbol for hydrogen. the symbol + represents the charge which is associated with the hydrogen. aq represents aqueous which means solution.
A range of values that are used to express the activity or alkalinity of system?
I think you mean the 'acidity', not the activity, of a system; in which case the answer is pH. pH is a measure of the acidity or alkalinity (how basic something is) of a system. pH values range from 1 to 14, with 1 being the most acidic and 14 the most basic. It works on a log scale; i.e., a pH of 2 is ten times more basic than a pH of 1.
