What happens when potassium hydroxide KOH and hydrochloric acid CL2 are combined? ASSUMING THE POTASSIUM HYDROXIDE IS DISSOLVE IN WATER, WHEN THE TWO SOLUTIONS ARE MIXED, THE DISSOCIATED H+ IONS FROM THE STRONG ACID (STRONG ELECTROLYTE) WILL PROTONATE, VIA HYDRONIUM IONS, THE HYDROXIDE IONS DISSOCIATED FROM THE POTASSIUM CATIONS (KOH IS A STRONG BASE, AGAIN, A STRONG ELECTROLYTE). THIS PROTONATION CREATES WATER (TWO WATER MOLECULES, ONE BEING THE CONJUGATE BASE OF THE HYDRONIUM ION AND ONE FROM THE COMBINATION OF H+ FROM THE HYDRONIUM ION AND OH- BONDING TOGETHER). POTASSIUM CHLORIDE STAYS AQUEOUS (A STRONG ELECTROLYTE), DISSOLVED AS K+ AND CL- IONS. HEAT IS RELEASED DUE TO THE DISSOCIATION OF HCL IF CONCENTRATED HCL IS ADDED TO THE SOLUTION OF KOH. HEAT IS RELEASED AS THE KOH DISSOCIATES AS WELL. THE PH WILL BE CLOSE TO 7 IF EQUIMOLAR SOLUTIONS WERE MIXED, DUE TO BEING A NEUTRALIZATION OF A STRONG ACID BY A STRONG BASE. KOH (AQ) + HCL (AQ) → H2O (L) + KCL (AQ) + HEAT
