Not simple to answer - acidic solutions contain more hydrogen ions that hydroxide ions, but there are very many ions that can cause hydrogen ions to be in excess - for instance the hydrogen-sulphate ion (from an acid salt such as sodium hydrogen-sulphate) when added to water has a tendancy to split into hydrogen and sulphate ions, so making the solution acidic. Not all acid salts are acid in soultion - for instance sodium hydrogen-carbonate is alkaline. When dissolved in water, the hydrogen-carbonate ion tends to react with hydrogen ions in the water to form molecular carbonic acid - removing hydrogen ions from the water and hence making it alkaline. Acid salts of strong acids, such as sulphuric, hydrochloric, nitric, are acidic in solution. Acid salts of weak acids, such as carbonic, sulphurous, are alkaline in solution. Just a few simple examples.

∙ 13y agoAcids form a positive and a negative ion in solution.
A useful definition of an acid is a substance that produces hydrogen ions. Hydrogen ions are positive, what remains of the acid is the negative ion.
Examples:
Hydrochloric acid HCl --> H+ + Cl- ; a hydrogen ion and a chloride ion
Sulphuric acid H2SO4 --> 2H+ + SO42- ; two hydrogen ions and a sulfate ion.
There is a lot more to the story of acids but basically knowledge of the hydrogen ion will get you by.

∙ 11y agoAn acidic solution will have excess of H+ ions. The total number of ions depends on the acid and the strength of the acid.

Which element can only form one ion?
which element can only formed one ion
What is Barium's oxidation state?
Barium is +2 valenced ion, so its oxidation state is +2 in ion form (Ba2+) and 0 in elemental (Ba) form
What would happen if ph5 was diluted by water?
The ph is a measure of the H+ve ion in the solution, the lesser the ph number means higher acidic the solution is where as the higher ph number means more of basic solution. If you add water to a solution with ph5 it will be introduced with more oh OH-ve ion which will make it first neutral(ph=7) or even basic in nature.
What is a pH table?
The pH of a solution measures the hydrogen ion concentration in that solution. A small change in pH represents a large change in hydrogen ion concentration. For example, the hydrogen ion concentration of lemon juice (pH of 2.3) is 63 times greater than that of tomato juice (pH of 4.1), and 50,000 times greater than that of water (pH of 7.0). mustki2005@yahoo.comNigerian
If Chlorine receives an electron from Sodium then Chlorine becomes a(n)?
The chloride becomes Cl-1 . When an ion is negative, it becomes an anion (or A Negative ION).
Which kind of compound increases the hydrogen ion concentration in a solution?
Acids increase the hydrogen ion concentration in a solution.
Which substances increase the H ion in a solution?
acids
Why might fatty acids amino acids and nucleic acids increase the hydrogen ion concentration of a solution?
The acids all contribute hydrogen ions to the solution.
Why might fatty acids nucleic acids and amino acids increase the hydrogen ion concentrated of a solution?
The acids all contribute hydrogen ions to the solution.

Which ion is furnished by acids in of agueous solution?
hydrogen ions
Which substances increase the H ion concentration a solution?

When acids in water what positive ion is produced in excess?
When acids in water hydrogen positive ion is produced in excess. It is this hydrogen positive ion that gives acidity of a solution.
Hydrochloric acid and acetic acid balanced chemical equation?
These two aCIDS DO not REACT, BECAUSE OF THE COMON ION (h^(+)) EFFECT,
What type of compounds form Lewis acids?
Any atom (or ion) or compound that can accept a pair of electrons to form a covalent bond.
What is a substance that yeilds a hydrogen ion when placed in a water solution?
These are acids.
General explanation for acid and alkali?
Acids receive electron. Alkalis donate. Acids donate hydrogen ion in solution. Alkalis donate hydroxyl ion in solution. Alkalis donate lone pair electrons.
