WebScore: 4.4/5 (36 votes) . In chemistry, a racemic mixture, or racemate (/reɪˈsiːmeɪt, rə-, ˈræsɪmeɪt/), is one that has equal amounts of left- and right-handed enantiomers of a chiral molecule.The first known racemic mixture was racemic acid, which Louis Pasteur found to be a mixture of the two enantiomeric isomers of tartaric acid. WebExplaining the conditions for the reaction. Remember that the reaction is done by reacting the aldehyde or ketone with a solution of sodium or potassium cyanide to which enough dilute sulphuric acid is added to give a pH of around 4 - 5. Hydrogen cyanide as a very weak acid. The initial attack on the carbonyl group is by a cyanide ion.
