Acetic acid / ə ˈ s iː t ɪ k /, systematically named ethanoic acid / ˌ ɛ θ ə ˈ n oʊ ɪ k /, is a colourless liquid organic compound with the chemical formula CH 3 COOH (also written as CH 3 CO 2 H, C 2 H 4 O 2, or HC 2 H 3 O 2).When undiluted, it is sometimes called glacial acetic acid.
We divide that by 1.8 x 10-5 And so, the Ka value is: 5.6 x 10-10 So if we get some room down here, we say: Ka = 5.6 x 10-10 This is equal to: so it''d be X squared over here And once again, we''re going to assume that X is much, much smaller than .050 So we don''t have to worry about X right here, but it''s an extremely small nuer, .050 - X is pretty much the same as .050 So we plug this in
6/6/2019· The debt-to-equity ratio (D/E) is an essential formula in corporate finance. It’s used to measure leverage (or the amount of debt a company has) compared to its shareholder equity.All companies have a debt-to-equity ratio, and investors and analysts actually prefer to
The given Ka and pKa do not match. But assuming the pKa is 3.8, we know that pH for a weak acid is given by pH = (pKa - log c)/2, where log is to the base 10. Substituting the given values in the expression, we get pH = (3.8 - log 0.1)/2 pH = (3.8
