Acid and Bases Flashcards
What is a Brosted- Lowry Acid?
A substance that can transfer hydrogen ions, H+; a proton donor
What is a Brønsted-Lowry Base?
A substance that can accept hydrogen ions, H+; a proton acceptor
What are conjugate Acid-Base Pairs?
Two substances on either side of the reaction that differ by 1 Hydrogen atom
What is an Amphoteric Substance?
A substance that can act as either an acid or base because they are both have a transferable Hydrogen and Nitrogen atom with lone electrons
Define Acid and Base Dissociation
Weak acids and bases partially dissociate and create an equilibrium
What structure does the Hydronium Ion prefer? Why?
Did to the high reactivity of the H ion, it is hydrated by one or more water molecules— preferring the H3O formation instead of H+
The stronger the acid, the smaller the____
pKa
Larger Ka=____
Smaller pKa
The stronger the base, the smaller the____
pKb
Larger Kb=
Smaller pKb
Strong acid + Strong base will shift in what direction of a rxn?
Towards the products, creating both weak acid and base
[HA] The weaker the bond…
The stronger the acid
[HA] The higher the electronegativity..
The stronger the acid
A solution is acidic if it’s pH is lower that what number?
7
When is the pH of a solution considered neutral?
When the pH is 7
