R,S-tartaric acid is a meso form. Tartaric acid 1 occurs in four forms: a pair of optically active enantiomers (+) (L-1), (–) (D-1) and racemic mixture (rac-1) as well as the symmetric form meso (meso-1). H 2 O . Compound meso-Tartaric acid , monohydrate with free spectra: 2 NMR and 1 FTIR. In tartaric acid there is plane of symmetry in b/w which divides the molecule into two equal halves thus making it a meso compund and hence optically inactive. Note that the meso form of tartaric acid did not play a part in Pasteur's experiments. It is optically idle because of inner remuneration for example the impact of one-portion of the particle is killed by other. Examine the meso form further. #��"�`�#��E�fK�`�7���,�Io ~� ��8B9��O�`\���uMt�!ꢢ��na����.���φ�,�k;�$ U�/��'T M&B�%�����#�9����p�]�f����X D8�o,D;�Ry�� P�4��K'Ru�y��Tgt�[�8�Я+�,N�u�0f���B�p"���!���,�_����Hc໴K���Nav�s�wƿ�"�,>���F>�fH�u�~"jй��a�%& ���XX�\��qKL�G`� =~�XoӍU'm�����@��v�Mf�Q��.�¦�Q6֫n`�k4�9'�'�� �%ĵ E��D�LQ�0>�Gؒ����p��yۭ������d��/�909�����w��ЯHFB�vd5��=��W���m����{c�.k����=�m����l����*�E��!�F^�|��}�T��ٵ��1B�,����.iq\��$Z���,�?3&=�O�,bB&4���A�G౦�pp��i?���ċ`��m� The solubility of l-tartaric acid was measured in ethanol, propanol, isopropanol, n-butanol, acetone and acetonitrile in the temperature range 281.15 and 324.25 K under atmospheric pressure by a gravimetric method.
