Is oxycodone acidic, basic, neutral, or amphoteric and how do you know?
How do you find a conjugate base or conjugate acid? For example, what its the congigate base of H2PO4-? Also, how would you find the congugate acid? Please explain simply, for some reason this topic is very confusing to me.
I know how to do the question, but at the very end, how do you
know if it's a buffer or not? What is the formula or rule to tell
if something is a buffer or not?
UBC Chem 123 Acid-Base Examples 20: Calculate the pH if 10.0 mL of 0.020 M benzoic acid is added to 40.0 mL of 0.004 M sodium benzoate. The pka of benzoic acid is 4.20. H₂O ² HA + benzoic acil - H₂ot +...
The ion HCO3- is amphoteric (can act as both a base and an acid when placed into water). Write the reaction that occurs in both instances. Include the correct charges on all ionic species. HCO3- acting as an acid HCO3- acting as a base
answer the following in a complete sentence or two (1)how do you know if an acid is strong or weak 2))how do youcalculate pH of a strng acid (3))how do youcalculate the pH of a weak acid solution (4) if you know Ka of an acid how do you determine the kb of its conjugate base 5)if you know[OH-]for solution ,how do you determine [h3o+].

a buffer is a solution that has a Weak acid in equlibirum with its conjugate base. So can a buffer solution has a weak base in equlibirum with its conjugate acid? So basically, to create a buffer, you can mix a weak acid with its conj. base OR a weak acid + strong base OR a weak base with a strong acid? Am i Correct?
how do I know if a compound is a base or an acid just by looking at its formula? i know how to determine acid and bases based on the whole equation, but it is hard to know just by looking at the compound, for example, Hco3, is it a base or an acid and how do we know, are there steps I can use? please give me examples with the explanation when I look at the formula for Hco3,...
