How do you make homemade nitric acid?
Dissolve 80 grams (2.8 oz) of nitrate salt in 50 millilitres (1.7 fl oz) of water. Start by portioning out your nitrate salt into a small glass mixing container. Then, pour in all of the water at once. Swirl the mixture around inside the container to help it dissolve faster.
How do you make platinum with nitric acid?
In general, the process for nitric acid manufacture consists of preheating the air, mixing it with ammonia gas, passing it over a platinum catalyst, extracting the heat produced from this reaction by using it to preheat the incoming air and then cooling further, adding secondary air and then absorb- ing the nitrogen …
Where is nitric acid found in nature?
The natural manner in which nitrates reach the soil involves the reaction of nitrogen gas and oxygen gas in the atmosphere to form nitrogen dioxide gas (NO2), which then reacts with atmospheric water, making nitric acid, which provides a natural source of nitrates in water and soil.

What is the pKa of HF?
HF is a strong acid relative to acetone . In water, the pKa of HF is about 3.45 relative to 20 (acetone). Compare pKa differences first, and then make your judgment. But Wikipedia does say that an acid with a pKa below −2 is generally a strong acid. Just remember that it’s relative to water.
What is the pKa of HCl?
E.g., Hydrochloric acid, HCl has a pKa = -3 Acetic acid, CH3COOH has a pKa = 4.77 A strong acid is one which is largely, or completely, dissociated, and which therefore has a high Ka value (and low pKa).
Is hydrogen fluoride a strong or weak acid?
HF (hydrogen fluoride, or hydrofluoric acid) is not a strong acid. It is a weak acid because it does not make many hydrogen ions available when it dissolves in water.
What is the antidote for HF?
Calcium gluconate gel, sometimes referred to as HF antidote gel, just may save your skin if you use hydrofluoric acid.
