Determining Brønsted acid strength using STRUCTURE and ARIO. IMPORTANT Label the acid and base on the left side of the arrow (be sure you explain how you made this Draw in the curved arrow(s) that show the electron movement associated with the most decision) likely proton transfer reaction. Show the products of this electron movement. Pay close attention to formal charge . Label the conjugate acid and conjugate base. ID the strong acid (SA), weak acid (WA), strong base (SB), and weak base (WB)-notice these terms are just relative and may apply only to this specific equilibrium Explain your thought process using ARIO Which acid would you expect to have the higher pKa value? Predict the equilibrium position (left vs. right vs. middle) for the equation shown, assuming that all starting materials were present at one molar concentration and STP at the beginning of the reaction. Which two species will be present in the highest concentration at equilibrium? . NH2 SeLi ClExplanation / Answer
A Brønsted-Lowry acid is any species that is capable of donating a proton.
A Brønsted-Lowry base is any species that is capable of accepting a proton, which requires a lone pair of electrons to bond to the H+.
Water is amphoteric, which means it can act as both a Brønsted-Lowry acid and a Brønsted-Lowry base.
Strong acids and bases ionize completely in aqueous solution, while weak acids and bases ionize only partially.
The conjugate base of a Brønsted-Lowry acid is the species formed after an acid donates a proton. The conjugate acid of a Brønsted-Lowry base is the species formed after a base accepts a proton.
The two species in a conjugate acid-base pair have the same molecular formula.
Acid base Equilibrium always favours to weaker acid and weaker base.
Ka is directly proportional to acidic strength and indirectly proportional to pka
Ka increases if no of -I,-R,-H affecting group increases.
