The ph of a certain orange juice is 3.36. calculate the h ion concentration.

The answer should be c.

Ithink is a because if say increased in electronegativity

☆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
