FAQ
Frequently Asked Questions
Yes, concentrated selenic acid is highly corrosive, toxic, and a strong oxidizer. It poses severe health risks upon contact and requires specialized handling procedures.
Its primary uses are as a strong oxidizing agent in specific chemical syntheses, in analytical chemistry for testing, and as a precursor for producing other selenium compounds.
No, it is a highly specialized and hazardous chemical not typically stocked in school laboratories. It is found in research or industrial chemical labs.
Selenic acid (H2SeO4) contains selenium in the +6 oxidation state and is a stronger acid and oxidizer. Selenous acid (H2SeO3) contains selenium in the +4 state and is weaker.
A strong, corrosive, inorganic acid containing selenium in its highest oxidation state (+6), with the chemical formula H2SeO4.
Selenic acid is usually technical/scientific in register.
Selenic acid: in British English it is pronounced /sɪˌliːnɪk ˈæsɪd/, and in American English it is pronounced /səˌlinɪk ˈæsɪd/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Think: 'SELENium' is the element, and '-IC ACID' indicates it's the acid form where selenium is in a high (+6) oxidation state, analogous to 'sulfuric acid'.
Conceptual Metaphor
CONCENTRATED POTENTIAL/CORROSIVE AGENT (e.g., 'Their criticism was like selenic acid, burning through every justification').
