Acid-Base Reactions • Acid – substance that increases the H+ concentration in aqueous solutions • HCl → H+ + Cl- • H2SO4→ H+ + HSO4- • HSO4→ H+ + SO42-
Base • Increases the OH- concentration • NaOH → Na + OH- • NH3 + H2O → NH4+ + OH-
Neutralization • Acids and bases react together to produce a salt (ionic compound) and water • HCl + NaOH → NaCl + H2O • Write a balanced equation for the reaction of hydrobromic acid, HBr, with barium hydroxide, Ba(OH)2.
Example • Write the reaction that occurs when hydrochloric acid is mixed with silver hydroxide
Write the balanced equation for the reaction between phosphoric acid and potassium hydroxide.
Examples • Aqueous acetic aceticacid is mixed with aqueous potassium hydroxide. Write the equation for the reaction.
Example • What volume of a .100M HCl solution is needed to neutralize 25.0 ml of .350M NaOH?
Example • In a reaction 28.0 ml of .250M HNO3 and 53.0 ml of .320M NaOH are mixed. Calculate the the amount of water formed.
