Question

1. Write the neutralization reaction for each of the following. Make sure to balance the equations. Please show all work. a. HI(aq) + NaOH(aq) ? b. HClO4(aq) + Sr(OH)2 ?

Explanation / Answer

Clue: the H of the acid and the OH of the base form water, that which remains forms a salt HCl + NaOH ---> H2O + NaCl 2HClO4 + Sr(OH)2 ----> 2H2O + Sr(ClO4)2 The formula for the salt is deduced from ion charges. In the first case you have Na+ and Cl^-. A 1:1 ion ratio is needed to balance charges- +1 + -1 = 0 In the second case, CLO4 is -1, but Sr is +2, so you must have 2 CLO4^-1 ions to match up with Sr+2. Since you must have 2, you have to put a 2 infront of HClO4 to balance the equation
