how much distilled water do I have to add to 2.5 g of Na2CO3 and 2.5...
2.95g of sodium bicarb how much water to add to make 1.0 M solution 4.25g of Sodium carbonate how much water to add to make 1.0 M solution. Please show all the work very clearly even little steps to help me understand. "You need to create a 1.0 M solution of sodium bicarbonate (NaHCO3 – baking soda). Your lab kit has a bag of sodium bicarbonate to use for this portion of the experiment. Write “sodium bicarbonate” on a sample...
You add 147.25g of potassium acetate (KCH3COO, MW 98.15 g/lol) to 250mL of distilled water. You adjust the pH to 5.5 with a volume of glacial acetic acid (17.4M, CH3COOH, pKa=4.75) and qs the remaining volume to 500mL with distilled water. How much glacial acetic acid did you have to add to make 500mL of a pH 5.5 buffer?
How much soda ash (Na2CO3) in kg/day do you need to add to remove calcium hardness from 200 mg/L CaCO3 to 50 mg/L CaCO3 if you have a water source with flowrate of 1000 m3/day. Consider the following unbalanced reaction that describes the process of Ca2+ removal. Ca2+ + Na2CO3 ↔ CaCO3↓ + Na+ Considering the soda ash has 96% purity and it costs $0.5/kg, how much would it cost the water treatment plant per year (365 days)?

dilution If I add 25 mL of water to 125 mL of a 0.15 M NaOH solution, what will the molarity of the diluted solution be? (Your answer should be written as 0.XXX with no units) Question 2 0.2 pts If I add water to 100 mL of a 0.15 M NaOH solution until the final volume is 150 mL, what will the molarity of the diluted solution be? (Your answer should be written as 0XXX with no units) Question...
a) Buffer solutions with a pH values of around 10 are prepared using sodium carbonate (Na2CO3) and sodium hydrogen carbonate (NaHCO3). What is the pH of a solution of 10.0g each of the two salts in enough water to make 0.250 L of solution? pKa2= 10.33 b) By how much does the pH change when 3.5mL of 6.0 M HCl is added? c) By how much does the pH of the solution change when 0.92 g of NaOH is added?
