hey mate , here's your answer....

•Boric acid is mixed with water to make weedicide sprays.

•Nickel metal dissolves slowly in dilute sulphuric acid to form solutions containing the aquated Ni(II) ion together with hydrogen gas, H2. In practice, the Ni(II) is present as the complex ion [Ni(OH2)6]2+. The strongly oxidizing concentrated nitric acid, HNO3, reacts on th surface of iron and passivates the surface.

...hope this helps...
