Midterm 3B

Postby Maya Gollamudi 1G » Sun Mar 15, 2020 6:21 am

How do you solve midterm question 3B? How do the concentrations affect delta T?

Which combination of solutions of HCl and NaOH would produce the largest ∆T? (3pt) Ans _____B
(A) 50 mL of 1 M HCl with 50 mL of 1 M NaOH
(B) 50 mL of 2 M HCl with 50 mL of 2 M NaOH
(C) 100 mL of 1 M HCl with 50 mL of 2 M NaOH
(D) 100 mL of 1 M HCl with 100 mL of 1 M NaOH

answer choice B is the most concentrated solution thus consisting of the least amount of water of the answer choices. Because water has a high specific heat capacity, meaning it takes more energy to heat, if we want to have the highest temperature change, it would be ideal if we can limit as much water as possible from the solution in order to heat it up faster.
