Ph of dilute sulfuric acid
Did you know?
Pure sulfuric acid is not encountered naturally on Earth in anhydrous form, due to its great affinity for water. Dilute sulfuric acid is a constituent of acid rain, which is formed by atmospheric oxidation of sulfur dioxide in the presence of water – i.e. oxidation of sulfurous acid. When sulfur-containing fuels such as coal or oil are burned, sulfur dioxide is the main byproduct (besides the chief p… WebNov 24, 2010 · The pH value of 98% sulfuric acid is approximately -1.5 For comparison, sulfuric acid of this concentration has about 300 times as many active hydrogen ions as …
WebMar 26, 2014 · If you dilute by 10 times, then the new p H will be 12, so you'll need to dilute it another 10 times to reach p H 11. If you start with 100 m l, you'll need to end with 10 litres in total ( 100 folds). You already have your 100 m l, so you'll need to add 10 000 m l − 100 m l … WebOct 11, 2024 · You are right. But the problem mentions "dilute solutions" . Baryum sulfate is known to be soluble in hot and concentrated sulfuric acid, because of the formation of $\ce{HSO4^-}$ ions. But $\ce{BaSO4}$ is not even soluble in hot concentrated hydrochloric acid, according to F.-P. Treadwell, Analytical Chemistry, 1924. $\endgroup$ –
