Neutralization exit ticket 1

The products of a neutralization reaction are most commonly...

• water & salt
• acid and base

• metal and salt

• carbon dioxide and water

Identify the salt produced in the following acid-base neutralization reaction: Zn(OH)₂ + HNO₃   ---> H₂O  + Zn(NO₃)₂

• Zn(OH)₂
• HNO₃
• H₂O
• Zn(NO₃)₂

Answer explanation

"salt" is a generic term to mean ionic compound between a metal and nonmetal OR between a metal and polyatomic ion.

Complete the following reaction (and be sure it is balanced):

HCl + KOH -->

• KCl + H₂O

• KCl + 2H₂O

• KH₂ + ClO

• 2KCl + H₂O

Complete the following reaction (and be sure it is balanced):

2HNO₃ + Ca(OH)₂ -->

• Ca(NO₃)₂ + H₂O

• Ca(NO₃)₂ + 2H₂O

• Ca(NO₃)₂ + H₂

• Ca(NO₃)₂ + H₂O + CO₂

The pH of solution after neutralization is

• 0

• 14

• 7

After a neutralization reaction...

• [H⁺] > [OH^-]

• [H⁺] < [OH^-]

• [H⁺] = [OH^-]

Answer explanation

[H⁺] = [OH^-] because the pH is at 7, neutral.

it is now the same pH as if it were pure, neutral water and in pure water [H⁺] = [OH^-]

(there is just some salt in the water too now)
