sulfur powder and acid

For the sulfur block, we can make that it can be transformed into 9 sulfur powder (or something similar to a powder) and make that we can brew it in water to have sulfuric acid. We can the fill a cauldron with a few of these and take the sulfuric acid in a cauldron. It will flow as fast water and even further. It will deteriorate blocks around it slowly, give poison and nausea to anything alive touching it and will make the copper corrode faster and break if fully oxidized. And for the poison effect from the liquid, we can make a command to change the option effect it gives by changing the bucket in hand with a command.
