How many gallons of 98% H2SO4 is necessary to neutralize 5000 gallons of NaOH?

Answer 1

What it the molarity of the NaOH? Pure NaOH is a solid. I assume you are talking about a solution of NaOH in water.

Pure NaOH solid usually is sold as powder or flake form, not in solid crystal gallons

Answer 2

Let me rephrase the question then. How much 98% H2SO4 is needed to neutralize 800 lbs of pure NaOH in 5000 gallons of water??
