Conjugate Acids And Bases Flashcards
Whenever and acid donates a proton to water…
The species is left behind is the conjugate base
The general equation for transforming an acid to a conjugate base is…
Acid + water —> conjugate base + hydronium ion
When a base accepts a proton from water…
The species created is called the conjugate acid of that base
The general equation for a base accepting a proton from water is…
Base + water —> conjugate acid + hydroxide ion
What is this compound?
H3O+?
Hydronium
When given a base and asked to find its conjugate acid, just…
Add a hydrogen ion to the formula
E.g.
Base : CO3^2-
Conjugate acid: HCO3^-1
When given an acid and asked to find its conjugate base, just…
Remove a hydrogen ion from the formula
E.g.
Acid: CH3COOH
Conjugate base: CH3COO^-1
Conjugate acids and bases only differ by…
1 hydrogen ion on either side of the reaction
Charge on conjugate acid is equal to…
Charge of base +1
Charge on conjugate base is equal to…
Charge in acid -1
The conjugate base of a strong acid is usually a…
Weak base
The conjugate acid of a strong base is usually a…
Weak acid
A weak base finds it hard to…
Accept protons
A weak acid finds it hard to…
Donate protons
The stronger an acid or base…
The weaker it’s conjugate is
The weaker acid or base…
The stronger its conjugate is
What are the 2 types of acids?
Bronsted and Lewis
Bronsted acids are labelled as…
Being able to donate protons
Lewis acids are labelled as…
Being able to accept an electron pair (much less common)
When a bronsted acid is dissolved in a solution…
They dissociate(ionise) and release hydrogen ions
Acids that donate 1 proton are…
Monoprotic
Acids that donate 1+ protons are…
Polyprotic
___________ creates lots of hydrogen ions and reacts easily
A strong acid creates lots of hydrogen ions and reacts easily
___________ doesnt make many hydrogen ions and reacts poorly
A weak acid doesnt make many hydrogen ions and reacts poorly
