hello friends, answer 》list some weak acids and strong acids?
Answers
When an acid dissolves in water, a proton (hydrogen ion) is transferred to a water molecule to produce a hydroxonium ion and a negative ion depending on what acid you are starting from.
In the general case . . .
These reactions are all reversible, but in some cases, the acid is so good at giving away hydrogen ions that we can think of the reaction as being one-way. The acid is virtually 100% ionised.
For example, when hydrogen chloride dissolves in water to make hydrochloric acid, so little of the reverse reaction happens that we can write:
At any one time, virtually 100% of the hydrogen chloride will have reacted to produce hydroxonium ions and chloride ions. Hydrogen chloride is described as a strong acid.
A strong acid is one which is virtually 100% ionised in solution.
Other common strong acids include sulphuric acid and nitric acid.
You may find the equation for the ionisation written in a simplified form:
This shows the hydrogen chloride dissolved in the water splitting to give hydrogen ions in solution and chloride ions in solution.
This version is often used in this work just to make things look easier. If you use it, remember that the water is actually involved, and that when you write H+(aq) what you really mean is a hydroxonium ion, H3O+.
hope this help you alot
❤❤❤Have a nice day❤❤❤
Some weak acid are
Ch3cooH ,oxalic acid or organic acid are generally weak
Strong acid are
sulfuric acid, nitric acid etc
