Question

when you add water to sulfur dioxide and put a blue litmus paper in it , why does it turn red?​

Answer 1

Answer:

Sulphur dioxide reacts to the addition of water, becoming acidic, that is an acid solution. It is then correctly names sulphuric acid. It will change the blue litmus paper to red, but if the litmus paper is red to begin with, the colour does not change.

Answer 2

Bases feel slippery, change litmus blue, and become less basic when mixed with acids.sic solutions.

Acids in water solutions show the following common properties: they taste sour; turn litmus paper red, and react with certain metals, such as zinc, to yield hydrogen gas.Bases in water solutions show these common properties: they taste bitter, turn litmus paper blue, and feels slippery. When a water solution of acid is mixed with a water solution of base, water and salt are formed, this process, called neutralization, is complete only if the resulting solution has neither acidic nor basic properties.
