What is the difference between concentration and activity?
Activity and Concentration • Activity - "effective concentration" • Ion-ion and ion-H2O interactions (hydration shell) cause number of ions available to react chemically ("free" ions) to be less than the number present • Concentration can be related to activity using the activity coefficient γ, where [a] = γ (c) we assume that activity, a, is equal to concentration, c, by setting γ = 1 when dealing with dilute aqueous solutions. But ions don't behave ideally . . . • Concentration related to activity using the activity coefficient γ, where [a] = γ (c) • The value of γ depends on: - Concentration of ions and charge in the solution - Charge of the ion - Diameter of the ion Activity coefficient γz → 1 as concentrations → 0
An ion that exits by itself is called a what?
Monatomic Ion, because Mono means One (1)
What are the key features of the chlorite ion model?
The key features of the chlorite ion model include a central chlorine atom surrounded by three oxygen atoms in a trigonal pyramid shape, with a negative charge of -1. This model helps to illustrate the arrangement of atoms and the overall charge of the chlorite ion.
What is the Bohr model of an ion of Boron?
The Bohr model of an ion of Boron would consist of five protons in the nucleus, as Boron typically has five protons. Electrons would fill the electron shells according to the rules of the Bohr model, with the number of electrons dependent on the charge of the ion (for example, Boron typically forms a 3+ ion, so it would have two electrons in its outer shell).
What ion is responsible for Make it basic sodium ion or hydroxide ion or hydrogen ion or water ion?
The hydroxide ion (OH-) is responsible for making a solution basic. It can combine with hydrogen ions (H+) to form water (H2O), reducing the concentration of free hydrogen ions and increasing the pH of the solution. Sodium ions (Na+) do not play a direct role in determining the pH of a solution.
What make is a Saturn Ion?
Saturn is the make, ion is the model.

What is the pH solution defined as what of the hydrogen ion concentration?
The pH is a measure of the activity of the ion H+ in a solution.
What has the author Ion M Oprea written?
Ion M. Oprea has written: 'Nicolae Titulescu's diplomatic activity'
What is the first activity of a prototype model?
test the model
An ion that exits by itself is called a what?
Monatomic Ion, because Mono means One (1)
What are characteristics of pH?
pH is the negative logarithm of the hydrogen ion activity in a solution.
Is pH chemical?
The pH is a measure of the hydrogen ion (H+) activity in a solution.

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).
What does a big change in the pH scale affect?
The activity of the ion H+ is severely changed.
What does the pH of a dilution measure?
pH is a measure of the hydrogen ion (H+) activity in a solution.
