Shreya adds some calcium hydroxide in a test tube containing concentrated sulphuric acid. The main product of the reaction will be:

Correct option is B

The correct answer is option ( b ) calcium sulphate

Information booster :

• When calcium hydroxide (Ca(OH)2\text{Ca(OH)}_2 Ca (OH)
  ​$$_2$$ ) reacts with concentrated sulfuric acid (H2SO4\text{H}_2\text{SO}_4 H2_22​​
  ​SO
  ​$$_4$$ ) , a neutralization reaction occurs.
• The primary product of this reaction is calcium sulfate (CaSO4\text{CaSO}_4 Ca SO$$_4$$​
  ​) along with water (H2O\text{H}_2\text{O}H
  ​$$_2$$​O).

Reaction:

Ca(OH)2+H2SO4→CaSO4+2H2O\text{Ca(OH)}_2 + \text{H}_2\text{SO}_4 \rightarrow \text{CaSO}_4 + 2\text{H}_2\text{O}Ca(OH)
​$$_2$$​+H
​$$_2$$​SO
​$$_4$$​→Ca SO$$_4$$​
​+2H
​$$_2$$​O
