I have two questions:

First, Does anyone know how to calculate the volume of sodium bicarbonate needed to nuetralize the pH of 250 gallons of 93% sulfuric acid, d=1.836? If so, can could someone double check my work below? Assume there is an endless supply of 100% sodium bicarbonate.

Here is what I have completed, let me know if this seems accurate:

93% of 946.35L = 880110ml H2SO4

880110ml x 1.836 = 1615882g H2SO4

1615882g/98.08g = 16476 moles H2SO4

16476moles/946.35L = 17.4M

946.35L X 17.4M X 2mol NaHCO3 X 84g NaHCO3 = 2766370.32g NaHCO3 or 6,098.8 lbs NaHCO3

In addition, I heard concentrated sulfuric acid does not need to be stored in a container with special lining because at the higher concentrations it does not corrode steel. If this is accurate can someone explain?

Thank You
