Identifying weak acids and strong acids - Khan Academy
Classify the acidity of acetic acid, CH 3 COOH , based on its reactivity in aqueous solution.
Ka and pKa review - Khan Academy
- We've already talked about how to write an equilibrium expression, so if we have some generic acid HA that donates a proton to H2O, H2O becomes H3O+ and HA turns into the conjugate base, which is A-. Here's our equilibrium expression and the ionization constant Ka for a …
Introduction to nucleic acids and nucleotides - Khan Academy
These polymers have a backbone of alternating ribose and phosphate groups, with nitrogenous bases forming ladder rungs. The sequence of nucleotides encodes genetic information, making nucleic acids fundamental to life.
Khan Academy
Strong acids/bases dissociate completely whereas weak acids/bases dissociate partially.
Factors affecting acid strength - Khan Academy
The relative strength of an acid can be predicted based on its chemical structure. In general, an acid is stronger when the H–A bond is more polar. Acidity is also greater when the H–A bond is weaker and when the conjugate base, A⁻, is more stable.
