Which of the following best describes an Arrhenius acid-base
reaction?
O A. Acid + base = H20
O
B. Acid + base = conjugate base + conjugate acid
O C. Acid + base = H+ + OH
O
D. Acid + base = salt + water

☆ionisation energy increases across a period from na -> ar☆ionisation energy decreases down a group from li -> fr☆ionic radius decreases across a period from na -> cl☆ionic radius increases down a groupfrom f -> ii hope it clarifies your doubts
