CHEM 1A Chapter Notes - Chapter 15.1-15.9: Litmus, Sulfuric Acid, Acid Strength
Document Summary
Basic solution base that creates additional oh+ ions again, still applies ph scale ph = log[h3o+] for log, number of sig figs into the log is the same as the number of decimal places coming out of the log poh + ph = 14. 00 pka smaller pka, stronger acid. Mixture of acids strong and weak: strong completely ionizes, suppresses addition h+ from ionization of weaker acid or autoionization of water, then calculate the formation of the weak acid two weak acids, if kas are sufficiently different in magnitude (several hundred), then assume weaker acid will not contribute to [h+] 15. 8 the acid base properties of ions and salts some ions act as bases e. g. hco3 anion a is conjugate base of acid ha every ion can potentially act as a base conjugate base of a weak acid is a weak base conjugate base of strong acid is ph neutral.
