2.6 Acids and Bases Intro Lesson Flashcards
What is an acid?
A proton donor
What is a base?
A proton acceptor
Why are strong bases good conductors?
Electrical conductivity requires free moving, charged particles. As strong bases fully
dissociate, they produce a high concentration of ions, and so have good electrical conductivity.
Why do weak acids have a higher pH than strong acids?
pH reflects the concentration of H3O+ ions. As weak acids only partially dissociate, the [H3O+] is lower, so they have a higher pH than strong acids.
Why are weak acids poor conductors?
Electrical conductivity requires free moving, charged particles. Weak acids only partially dissociate in water, forming a lower concentration of ions, resulting in poor electrical conductivity.
Why do strong acids have a lower pH than weak acids?
pH reflects the concentration of H3O+ ions. As strong acids fully dissociate, the [H3O+] is high, so they have a lower pH than strong acids.
