Lub dilute acid tau siv los ua ib qho yooj yim xeem rau kub . Aqua regia, sib tov ntawm ib ib feem ntawm nitric kua qaub thiab peb feem ntawm hydrochloric acid yog ib ntawm lawv.
Tom qab ntawd, xim dab tsi kub hloov nrog acid?
Cov Acid Test Ua ib lub cim me me rau ntawm daim kub nkag mus rau saum npoo. Tso me me ntawm cov kua nitric kua qaub ntawm qhov khawb thiab tos kom muaj tshuaj tiv thaiv. cuav kub yuav tam sim ntawd tig ntsuab qhov twg kua qaub yog. Kub -over-sterling nyiaj yuav dhau los ua milky zoo li.
Yuav ua li cas ntxuav kub nrog acid?
