Acid-rock drainage at Skytop, Centre County, Pennsylvania ...
Acid-rock drainage is the water-quality hazard resulting from the oxidation of iron sulfide minerals (Nordstrom and Alpers, 1999). The pH of acid-rock drainage typically ranges from 2 to 4, but can range to values as high as 8 and as low as -5 (Plumlee and others, 1999; Nordstrom and Alpers, 1999). Many metals are more

Why is sandstone so resistant to acid rain? | Yahoo Answers
Mar 02, 2012· The only acid which reacts with SiO2 is HF which is not present in acid rain. In addition SiO2 is a theoretical acid anhydride with "acidic" potential so it is not prone to acting with other acids. Limestone by contrast is subject to corrosion by sulfuric and carbonic acids due to the tendency of CO3= to be a proton acceptor.

A standard, or generic HCl-HF acid mixture cannot, therefore, be used indiscriminately. In many cases, standard mud acid (12% HCl-3% HF), or even half-strength mud acid mixtures (6% HCl-1.5% HF, or 7.5% HCl-1.5% HF), which have gained popularity recently, will be damaging to a particular formation because of excessive dissolution by HF.

Is sandstone a soft rock? | AnswersDrive
Silica cemented sandstone is very durable and hard. Calcite cemented sandstone is subject to acidic dissolution and is more easily eroded. Clay and gypsum cements, which are soft minerals, tend to produce much softer sandstone and the sand can sometimes be rubbed off in a person's hands.
