WebWhen an Arrhenius acid is dissolved in water, it produces. 1) H+ as the only positive ion in solution. 2) NH3+ as the only positive ion in solution. 3) OH- as the only negative ion … WebWhen a strong acid is neutralized by a strong base there are no excess hydrogen ions left in the solution. The solution is said to be neutral as it is neither acidic nor alkaline. The pH of such a solution is close to a value of 7; the exact pH value is dependent on the temperature of the solution. Neutralization is an exothermic reaction.
