What is the principle of Le Chatelier regarding equilibrium?
Click to flip
Le Chatelier's principle states that a system at equilibrium will adjust to counteract changes in concentration, temperature, or pressure.
Click to flip
What is a weak base, and can you give an example?
Click to flip
A weak base partially accepts protons; an example is ammonia (NH₃).
Click to flip
What is the difference between strong and weak acids?
Click to flip
Strong acids fully dissociate in water, while weak acids only partially dissociate.
Click to flip
Explain the role of an acid-base titration.
Click to flip
An acid-base titration is used to determine the concentration of an acid or base by reacting it with a solution of known concentration.
Click to flip
Why is the equivalence point important in a titration?
Click to flip
It's the point at which the amount of acid equals the amount of base, allowing the calculation of unknown concentration.
Click to flip
What is the Ka value indicative of?
Click to flip
Ka value indicates the strength of an acid; larger Ka values mean stronger acids.
Click to flip
What is the relationship between Ka and Kb?
Click to flip
For a conjugate acid-base pair, the product of Ka and Kb is equal to the ion product of water, Kw (1.0 x 10⁻¹⁴ at 25°C).
Click to flip
Why might a strong base be used in industrial cleaning?
Click to flip
Strong bases can effectively break down and dissolve organic materials and grease.
Click to flip
What are amphiprotic substances?
Click to flip
Amphiprotic substances can both donate and accept protons.
Click to flip
During neutralization, what two products are commonly formed?
Click to flip
Neutralization typically forms water and a salt.
Click to flip
What happens at the molecular level in an acid-base reaction?
Click to flip
Protons are transferred from the acid to the base.
Click to flip
What is a polyprotic acid, and give an example?
Click to flip
A polyprotic acid can donate more than one proton per molecule, such as sulfuric acid (H₂SO₄).
Click to flip
What is the autoionization of water?
Click to flip
Autoionization of water is the process where water molecules spontaneously form H⁺ and OH⁻ ions.
Click to flip
What is the common ion effect?
Click to flip
The common ion effect occurs when a given ion is added to an equilibrium system, impacting the extent of dissociation.
Click to flip
Why is the Haber process relevant to acid-base chemistry?
Click to flip
The Haber process involves the production of ammonia, a weak base, from nitrogen and hydrogen.
