Yes, it will affect the experimental value of Ksp and ∆H° ,
And it will falsely high than ture value
Explanation: if it is taken in large or excess amount, then it will take longer time to reach the end point of titration which implies more amount of titrating agent will be consumed and therefore reaction will continue till all amount of solid taken undergo reaction,

The depreciation rate is 3%. The saving rate, s, depends on the level of capital per worker, k, as follows: 5% if k < 5 (7k-30)% if 5 < k < 10 40% if k > 10 8 There are three steady states with k > 0:...

Question 3 A travel channel film series of video clips in various cities in America. The demand for travel videos is uncertain: it is high 50% of the time and low 50% of the time. The firm hires labor in the city where it is filming, to help produce the clips. In a large city, the firm always pays $15/hour. It hires 10 workers when demand is low, and 30 workers when demand is high. In a small city, the...
