gain of electrons

Question 10

salt

Answer 10

product of a reaction in which H+ ions from acid are replaced by meta, or ammonium ions

Question 11

strong acid

Answer 11

dissociates completely in solution

Question 12

weak acid

Answer 12

acid that dissociates only partially in solution

Question 13

alkali

Answer 13

dissolved in water releasing OH- ions
