Acids & Bases Flashcards

All 5 cards in this deck

What ions do acids produce in solution?: Hydrogen ions, H⁺.
What ions do alkalis produce in solution?: Hydroxide ions, OH⁻.
e.g. sodium hydroxide is a source of OH⁻ ions.
What name is given to the reaction between an acid and an alkali?: Neutralisation (it is exothermic).
What is the ionic equation for acid–alkali neutralisation?: $H^+ + OH^- \rightarrow H_2O$
How do the concentrations of H⁺ and OH⁻ ions compare in a neutral solution (pH 7)?: They are equal.
