Iodine
Nobody 'invented' iodine ,it was discovered. In 1811 Bernard Courtois accidentally discovered iodine. The discovery was announced in 1913.He used to extract saltpetre from seaweed, afterwards destroying the waste with sulfuric acid. One day, he added too much sulfuric acid, which caused a cloud of purple vapour to form. He saw that it crystallized on cold surfaces, but he had no money to pursue the discovery. He passed some of the sample to chemist friends of his, who isolated the new element and determined its properties. The most well-known of these were Joseph Louis Gay-Lussac and Sir Humphrey Davy, both of whom claimed identification but credited Courtois with the discovery.
Nothing.
Naked roasted seaweed -- not doctored seaweed with oils added -- is very, very low in calories. It is like eating naked lettuce.
Adding sulfuric acid to water is the recommended way of working to avoid accidents.
Sulfuric acid is added to sugar to make carbon
hydrogen gas evolved
No.
It depends on what has been added or how dilute it is.
The color is orange to red.
Benzocaine is formed
