(2) HCl was left to stand for 5 minutes and then the temperature was taken
(3) Steps 1-2 was repeat with NaOH instead of HCl,
(4) NaOH was added to HCl in polythene cup and stirred for 5minutes and the highest temperature the liquid rose to was recorded.
Results: Initial temperature of NaOH - 32˚
Initial temperature of HCl - 31˚
Final temperature of mixture…
