Merhaba arkadaşlar birkaç sorum var acaba yardımcı olabilir misiniz? Şimdiden teşekkür ederim 1. A water sample contains 40 mg/L of ammonium (NH4+ ). The equilibrium pH of wastewater is measured around 9. Calculate the alkalinity and acidity of water sample in mg/L CaCO3. 2. A water sample from the overflow of the recarbonation basin has a pH of 9. 200 ml of water sample requires 1,1 ml of 0.02 N H2SO4 to titrate it to phenolphthalein end-point and continuing with the titration an additional 22,9 ml of 0.02 N H2SO4 is required to titrate it to the methyl orange end-point. Calculate the total and carbonate alkalinity of that solution. 3. 10 grams limestone (CaCO3) is added to 1-Liter DI water. The solution containing 10 g limestone is heated up to 90° C under mechanical mixing. Estimate the total hardness of this solution as mg/L CaCO3.
