Acid Basics
This term refers to a substance that donates H⁺ ions according to the Brønsted–Lowry model.
What is an acid?
This type of acid breaks apart into ions 100% in water.
What is a strong acid?
This term describes an acid releasing H⁺ into water.
What is ionization?
This type of acid donates exactly one proton (H⁺).
What is a monoprotic acid?
This is the dissociation equation for nitric acid.
What is HNO₃ → H⁺ + NO₃⁻ ?
This scale is used to measure how acidic or basic a solution is.
What is the pH scale?
This is the main reason weak acids ionize only partially.
What is weak H–A bonding or equilibrium resistance?
his happens to pH when the amount of hydrogen ions increases.
What is pH decreases?
This type of acid donates its two hydrogen ions one at a time.
What is a diprotic acid?
This is the dissociation equation for acetic acid.
What is CH₃COOH ⇌ H⁺ + CH₃COO⁻ ?
This property describes an acid that completely separates into ions when dissolved.
What is complete dissociation?
This strong acid is commonly used in car batteries.
What is sulfuric acid?
This type of arrow indicates ionization that can go forward and backward.
What is the reversible arrow (⇌)?
This type of acid has three ionizable hydrogens.
What is a triprotic acid?
This is the first dissociation step of oxalic acid.
What is H₂C₂O₄ ⇌ H⁺ + HC₂O₄⁻ ?
This term describes acids found in food and the human body.
What are organic acids?
This weak acid is responsible for the fizz in soft drinks.
What is carbonic acid?
This point on a titration curve shows that the acid and conjugate base are equal in amount.
What is the half-equivalence point?
This common diprotic acid is responsible for acid rain formation with CO₂.
What is carbonic acid?
This is the second dissociation step of carbonic acid.
What is HCO₃⁻ ⇌ H⁺ + CO₃²⁻ ?
This property of acids allows electricity to flow through their solutions.
What is the presence of ions?
This concept explains why a weak acid can still have a low pH if concentrated.
What is acid concentration?
This happens to the pH when each H⁺ of a diprotic acid is neutralized.
What is a separate rise or jump in pH?
This fruit acid is triprotic and important in metabolism.
What is citric acid?
These are the three general dissociation steps of any triprotic acid (H₃A).
What is:
H₃A ⇌ H⁺ + H₂A⁻
H₂A⁻ ⇌ H⁺ + HA²⁻
HA²⁻ ⇌ H⁺ + A³⁻ ?
