A method known as multiple tube fermentation technique is used to check biological water quality. With reference to it choose the correct statements and use the following table for MPN calculations: Size of sample (ml) No. of positive tubes No. of negative tubes 1 4 1 0.1 2 3 0.01 2 3 0.001 1 4 Correct Option Most probable number is a number which represents the bacterial density, which is most likely to be present in the water. B The coliform actually is gram-negative, non-spore farming rod shaped bacteria that ferment lactose and the end products are alcohol and CO2. Volume of sample in negative tube is 1.334 ml. Correct Option MPN/100 ml using Thomas equation is 331. Correct Option

Problem 4. A receipt of surface water sample is given in Table below: Substance Concentration (mg/L) Total Hardness 1000 mg/L CaCO3 Phenolphthalein acidity 5 mg/L CaCO3 Phenolphthalein Alkalinity 3 mg/L CaCO3 It is known that phenolphthalein alkalinity is only due to CO3²- and phenolphthalein acidity is only due to H₂CO3. Assuming the hardness of sample is because of calcium and magnesium ions, alkalinity-acidity are due to the carbonate species, calculate: a) The pH of sample. b) Temporary and permanent hardness as mg/L CaCO3. c) Total alkalinity and acidity as mg/L CaCO3. Molecular weights (g/mole): Ca = 40, Mg = 24, H = 1, C = 12, 0 = 16
6. Identify the two species within the carbonate system that are the most relevant to the following situations, and identify the associated equilibrium constant: a. Dissolution of an Alka-Seltzer tablet (sodium bicarbonate, citric acid, aspirin) in water to create an effervescent pain-relieving drink. b. The effects of ocean acidification on the health of coral reefs.
In determination of Acidity experiment, If the volume of 0.02N NaOH when use Methyl Orange (M.O) is 0.8 mL and 7.8 mL when use Phenolphthalein (Ph.Ph), the volume of sample is 25mL and the EW for CaCO3 is 50. The Mineral Acidity as mg (CaCO3)/L is
