I got #1. Please answer as many parts as possible thank you!
A water sample was analyzed and was found to have the following constituents (same analysis as for part of the homework) Ca2, mg/L 123 Mg2, mg/L 12 Na", mg/L 22.1 K', mg/L 3.8 Fe, /L 5.8 Mn2, mg/L 1.5 HCO, mg/L 82 SO,2. mg/L 122 CI, mg/L 112 CO,2, mg/L 6.0 I emperature 25°C 1. Calculate the alkalinity (exactly). 2. Calculate the total, carbonate, and non-carbonate hardness of the water include contributions made by iron and manganese). How many mL of 0.02N H,SO, would be required to neutralize the bicarbonate alkalinity in a 50 mL sample? 4. Draw a bar chart for the water (see pages 287-288 for an example). 5. Based on the solubility product for calcium carbonate, how much calcium (mg/L as CaCO,) should be soluble in this water? Is the water under-saturated or over-saturated with respect to calcium? 6. Based on the solubility product for magnesium hydroxide, how much magnesium (mg/L as CaCO,) should be soluble in this water? Is the water under-saturated or over-saturated with respect to magnesium?
