Question 6

A technician completely neutralises dilute sulfuric acid with sodium hydroxide solution. Sodium sulfate and water are formed.

What is the balanced symbol equation for this reaction?

[1]
A

2NaOH+2H2SO4→Na2SO4+2H2O\mathrm{2NaOH + 2H_{2}SO_{4} \rightarrow Na_{2}SO_{4} + 2H_{2}O}2NaOH+2H2​SO4​→Na2​SO4​+2H2​O

B

2NaOH+H2SO4→Na2SO4+H2O\mathrm{2NaOH + H_{2}SO_{4} \rightarrow Na_{2}SO_{4} + H_{2}O}2NaOH+H2​SO4​→Na2​SO4​+H2​O

C

NaOH+H2SO4→Na2SO4+H2O\mathrm{NaOH + H_{2}SO_{4} \rightarrow Na_{2}SO_{4} + H_{2}O}NaOH+H2​SO4​→Na2​SO4​+H2​O

D

2NaOH+H2SO4→Na2SO4+2H2O\mathrm{2NaOH + H_{2}SO_{4} \rightarrow Na_{2}SO_{4} + 2H_{2}O}2NaOH+H2​SO4​→Na2​SO4​+2H2​O
