Final answer:
Amoxicillin is the penicillin that provides good oral absorption and is effective against most common gram-positive and gram-negative bacteria.
Step-by-step explanation:
The penicillin that provides good oral absorption and is effective against most common gram-positive and gram-negative bacteria is amoxicillin.
The major oral penicillins, including penicillin V, ampicillin, and amoxicillin, are acid-stable, allowing them to be administered orally.
Amoxicillin is a form of aminopenicillin that has an expanded spectrum of activity against gram-negative pathogens. It also has increased acid stability, which improves its oral absorption.
