MCQ
When $50\,c{m^3}$ of a strong acid is added to $50\,c{m^3}$ of an alkali, the temperature rises by ${5\,^o}C$. If $250\,c{m^3}$ of each liquid are mixed, the temperature rise would be.....$^oC$
  • $5$
  • B
    $10$
  • C
    $25$
  • D
    $20$

Answer

Correct option: A.
$5$
(a)No doubt heat evolved during neutralisation of $250\,c{m^3}$of each acid and base is five time the heat evolved during neutralisation of $50\,c{m^3}$of each acid and base but the quantity if solution taking heat is also five time thus same temperature rise is noticed.
