What will be the influence of using more alkaline/acidic water in boilers? Discuss the type of corrosion resulting from it and their method of prevention. (b) Calculate the hardness in a given hard water sample having the following data. 50 ml of standard hard water containing 1 mg of CaCO3 per ml consumed. 50 ml of standard hard water consumed 25 ml EDTA using eriochrome black T as indicator. 50 ml water sample consumed 40 ml EDTA using the same indicator. 50 ml water sample after boiling consumed 25 ml of EDTA using the same indicator. (c) Discuss the problems of boilers which can be arises due to use of high concentration of alkaline substance along with their prevention and disadvantages.
