FOLLOW-UP QUESTIONS 1. A certain soft drink was analyzed and found to contain 0.080MH. Other ingredients of the drink include sugar or, in the diet form of the drink, an artificial sweetener. What property of this acid solution is overcome by using sugar or sweetener? 2. Every day, a manufacturing plant produces 5.0 x 103 L of NaOH waste of molarity 0.030 M. In order to comply with environmental regulations, this NaOH must be neutralized before being discharged as effluent. What mass of concentrated HCl will be required to neutralize it? ([HCI] = 12M; density = 1.2 kg/L) 4. Why would it be difficult to measure e concentration of acid in red wine or in a cola-type drink using the method in Part V? How could you overcome this difficulty? 5. There are some titrations in which the endpoint is obtained by measuring the electrical conductivity of the solution and watching for the point at which the conductivity is at a minimum. Such a titration is called an electrometric titration. An…
