Please answer this question; 30.00 ml of a 0.01 M caustic potash solution, was completely neutralized by 25.00 ml of a sulfuric acid solution. What would be the amount of barium chloride required to quantitatively precipitate the sulfate in 100 ml of this sulfuric acid solution?(relative atomic masses Ba=137; K=39; Cl= 35.5; S=32; O=16; H=1)

*tilts head* sounds more like a statement

- "the choice that is not an indicator of a chemical change is "state of matter changes". more common than not, chemical reactions produce energy in the form of light or heat. along with energy, they also produce a new substance called the product that could be in any state of matter (solid, gas, or liquid)."

the answer is 75.0%.
