Answer: The equivalent mass of the acid is 83.16 grams
Explanation:
To calculate the number of moles for given molarity, we use the equation:
Molarity of solution = 0.1165 M
Volume of solution = 24.68 mL = 0.02468 L
Putting values in equation 1, we get:
( as acidity of NaOH is 1)
For end point: gram equivalents of acid = gram equivalents of base =
Mass of acid=
Thus equivalent mass of the acid is 83.16 grams
Answer: The temperature rise is
Explanation:
The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.
Q = Heat absorbed by ice = 5280 J
m = mass of ice = 2.40 kg = 2400 g (1kg=1000g)
c = heat capacity of water =
Initial temperature =
Final temperature =
Change in temperature ,
Putting in the values, we get:
Thus the temperature rise is
