Flashcards in Chapter 13- Acid Base Deck (21):
Properties of acids
Usually taste sour
Are moelcular in structure and dissolve in water to produce an electrolyte
Neutralised by bases
Properties of bases
-Usually taste bitter
-Usually insoluble in water
Acid ....... a proton (H+ ion)
Base....... a proton (H+ ion)
What is an ionisation reaction?
A reaction in which a substance reacts with water to produce ions.
When one substance reacts with water to form OH- or H3O+ ions
Explain the process of neutralisation
Process of an acid reacting with a base, produces a salt and water.
What are spectator ions?
ions that do not take part in the reaction
Conjugate acid-base pairs
The substance acting as an acid gives away the proton forms a conjugate base. The substance acting as as base after accepting a proton forms a conjugate acid.
Define polyportic acids
Acids that can donate more than one proton per molecule untill acid
Substances that can act as either acids or bases, such as water
Explain self ionisation in reagrds to water
Water ca react with itself as it can act as both an acid and a base.
Explain the difference between a strong acid and a weak acid
-indicates how readily an acid donates protons
-stronf acids form large number of ions in water and form solutions that are good conductors of electricity
-Weak acids do not donate protons as readily
-As a result few ions are formed by reaction and resulting in poor electrical conductor.
What does the pH scale range to
what does pH equal
Causes the oxidation of another substances and itself is reduced
is tha species that causes reduction of another substance and it itself is oxidised
