-1Question 2
According to the Arrhenius theory, a neutralization reaction involves:
◦ the combination of hydrogen ions and hydroxide ions to form water
◦ the dissociation of a strong acid to hydrogen ions and an anion
◦ the dissociation of a strong base into hydroxide ions and a cation
◦ the addition of water to ammonia to make ammonium hydroxide
◦ the combination of an acid with a base to make only water
