A metallurgical firm needs to dispose 2.77 of gallons of waste sulfuric acid whose concentration has been determined to be 2.10

Alchen [17]

Answer:

It will cost 1.9$ to neutralize the waste sulfuric acid

Explanation:

Step 1: The neutralization reaction

H2SO4(aq) + Ca(OH)2 (s) → CaSO4(s) + 2H2O

Step 2: Calculate the molar mass of Ca(OH)2

Molar mass of Ca = 40.08 g/mole

Molar mass of O = 16 g/mole

Molar mass of H = 1.01 g/mole

Molar mass of Ca(OH)2 = 40.08 + 2*16 + 2*1.01 =74.1 g/mole

Step 3: Convert gallons to liters

2.77 gallons of H2SO4 = 10.48559 Liters H2SO4

Step 4: Calculate number of moles of H2SO4

Molarity = moles / liters

2.10 M = moles / 10.48559L

number of moles = 2.10 * 10.48559 =22.02 moles

Step 5: Calculate the number of moles of Ca(OH)2

H2SO4(aq) + Ca(OH)2 (s) → CaSO4(s) + 2H2O

For 1 mole of H2SO4 consumed we need 1 mole of Ca(OH)2

This means we need 22.02 moles of Ca(OH)2

Step 6: Calculate mass of Ca(OH)2

mass of Ca(OH)2 =number of moles * Molar mass of Ca(OH)2

mass of Ca(OH)2 = 22.02 moles * 74.1 g/moles = 1631.682 grams

Step 7: Convert grams to pounds

1631.682 grams/ 453.592 = 3.5972 pounds

Step 8: Calculate the cost

price Price per pound = 0.53$

Price for 3.5972 pounds = 0.53 * 3.5972 = 1.906516 ≈1.9$

It will cost 1.9$ to neutralize the waste sulfuric acid
