The calcium salt produced by the reaction of the sulfuric acid and calcium hydroxide is calcium sulfate which in turn causes an increased degradation due to sulfate attack. This process is illustrated below. H 2 SO 4 + Ca(OH) 2 Ca(SO) 4 + 2H 2 O. Acid + Calcium Hydroxide Calcium Sulfate+ Water (calcium sulfate product contributes to sulfate attack)

Hydrogen gas is not evolved when metals react with nitric
See the explanation When metals react with nitric acid hydrogen gas is liberated. Nitric acid is a very strong oxidizing agent. So , it oxidizes the hydrogen gas formed during the reaction to form water and an oxide of nitrogen (NO , N_2O , NO_2" etc." ). The reaction for it is:- Zn + 4HNO_3 -> Zn(NO_3)_2 + 2NO_2 + 2H_2O Exception:- Magnesium and manganese react with very dilute nitric acid to
Acid rain - Wikipedia
Acid rain is a rain or any other form of precipitation that is unusually acidic, meaning that it has elevated levels of hydrogen ions (low pH).It can have harmful effects on plants, aquatic animals, and infrastructure. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide, which react with the water molecules in the atmosphere to produce acids.

Nitric acid is also commonly used as a strong oxidizing agent. Pure anhydrous nitric acid (100%) is a colorless mobile liquid with a density of 1.512 g/cm2 that solidifies at -42° C and forms white crystals. It boils at 83° C. Consequently, anhydrous nitric acid should be stored below 0°C to avoid decomposition.
