Give an example of a monoprotic acid?
Monoprotic: HCl, CH3COOH (acetic acid)Diprotic: H2SO4, HOOCCOOH (oxalic acid)Triprotic: H3PO4, C3H4OH(COOH)3(citric acid)(All acidic protons are bold)
What is an acid containing one ionizable hydrogen ions?
An acid containing one ionizable hydrogen ion is called a monoprotic acid. This means that it can donate one hydrogen ion (H+) when it dissolves in water. Examples of monoprotic acids include hydrochloric acid (HCl) and acetic acid (CH3COOH).
Is the enthalpy change of the chemical reaction between a monoprotic acid and sodium hydroxide the same for all strong monoprotic acids?
The reaction that occurs between a strong monoprotic acid and sodium hydroxide is H++OH- => H2O. This reaction is the same for all strong monoprotic acids and sodium hydroxide so, in theory, they should all have the same standard enthalpy of reaction. In practice, there are very slight differences between acids. If you are in a freshman or sophmore chemistry class, say yes. If you are in physical or analytical chemistry say no.
When the solid acid dissolves to form ions how many moles of H plus ions are produced for every mole of acid used?
It depends on the acid being used. For monoprotic acids, like HCl or HNO3, one mole of acid produces one mole of H+ ions. For diprotic acids, like H2SO4, one mole of acid produces two moles of H+ ions.
How do i calculate pH given the acid constant?
For a weak acid, HA...HA ==> H^+ + A^- Ka = [H+][A-]/[HA] Plug these values into the Ka equation. You also must know the [HA] that you start with. Solve for [H+] Take -log [H+] = pH
