Acids and Alkalis formula quiz

Question 1 of 7

1

What is the standard formula for a neutralisation reaction?

Select one of the following:

  • Acid + Water = salt + base

  • Acid + base = salt + water

  • Base + salt = acid + hydrogen

  • Acid + base = salt + hydrogen

Explanation

Question 2 of 7

1

How is a neutralisation reaction written in terms of H+ and OH- ?

Select one of the following:

  • H2O + H+ = Water + OH- +salt

  • OH- +salt = H+

  • H+ + OH- = H20

  • Water + H+ = OH- +H2O +salt

Explanation

Question 3 of 7

1

What is the formula for reacting an acid with a metal?

Select one of the following:

  • Acid +metal = salt + hydrogen

  • Acid + metal = salt + water

  • Acid + salt = metal + water

  • Water + salt + metal = acid

Explanation

Question 4 of 7

1

Which one of these is the correct balanced equation for the reaction between Hydrochloric acid (HCl) and Magnesium (Mg)? (Sorry no subscript)

Select one of the following:

  • HCl + Mg = MgCl2 +H2

  • 2Hcl + 2Mg = MgCl2 + H2

  • HCl + 2Mg = 2MgCl2 + 2H2

  • 2HCl + Mg = MgCl2 +H2

Explanation

Question 5 of 7

1

Which of these is the correct equation for the manufacture of Ammonium Nitrate (NH4NO3)? (sorry no subscript)

Select one of the following:

  • NH3 + 2HNO3 = NH4NO3

  • NH3 + HNO3 = NH4NO3

  • 2NH3 + 2HNO3 = NH4NO3

  • NH3 + 2HNO3 = 2NH4NO3

Explanation

Select one of the following:

  • Salt + hydrogen

  • Salt + water

  • Salt +Water hydroxide

  • Salt hydroxide +water

Explanation

1

Therefore, HCl + NaOH = ?

Select one of the following:

  • NaClOH + H2O

  • NaCl + H2OOH

  • NaCl + H2

  • NaCl +H2O
