When H+ concentration is increased as in acidosis, H+ ions are secreted (preferentially over K+ ions) in exchange of Na+Thus in acidosis K+ secretion into tubules (excretion) is inhibitedRef: Harrison's 18/e p366
Has biphasic effect on K+ excretion
Does not effect K + excretion
Decreases urinary K+ excretion
Increase urinary K+ excretion
