PbI₂ (precipitate color) Yellow. I tried the suggestion given by X. Ramón Nóvoa , and I noticed that it worked. %��������� You are lucky that your junction was not obstructed in the contact. In said Luggin you would put your electrolyte solution, but without the silver salt (so just H3BO3 + HNO3).

In the cases of iron(III) and copper(II), reduction in neutral and basic pyrop... Electrochemical studies of hydrogen peroxide were carried out at a platinum disc electrode under quiscent and steady state conditions, in the pH range of 2–12.3 in an universal buffer medium. 0.5M H2SO4 was taken as the supporting electrolyte. << /Length 5 0 R /Filter /FlateDecode >> How can i repare an Ag/AgCl reference electrode ? You could use a bridge tube (not a true salt bridge, but effectively the same) which can serve the same function but are terminated with a frit, which would help with that transition. Because the Luggin Capillary which I have is a kind of simple bent capillary which does not contain any plugs to retain the electrolyte within it. Or I can simply chloridize the whole silver. Now we are going to list all precipitates according to the s block, p block and d block and colours. Usually platinum is used as counter electrode, and sometimes i see silver and gold are also used as counter electrode. x�]͒#����)j�Ď�P�_�ޓ=�K��dž������9�}J?�~���UY�t˖� |�H$2 ���/��EY�?�v[l�m�x(�Z_�}*���b���C���j�L6UQ�Ve�^W����n�V��ۏ�׷��.n*�]uS��o��[~bi�\�TLU��49H�v���.�-�>��z�.�����hJf���Ζ�ٿ˷�7E],7ES,?�o�by�)�b�t�h��3~�)��W�b6Ų�f��R��������b�)y���S�����$�LS��S��'�b8���7*�yo|���{�A٬�FYx�L\W��v�L�?��:0���f�,�΀7�+�N���ko�|(������i�"���պ�r��t�H�6�]�P�z�������x~x䛺[A����{!�&���O�l�P�U�]U%�Yז2Ia��0S�PӬ� �z���7��+�2���w.�m���|fJ�K)�J��H����*�.��4�- �qS9h��q�L*˪~2wͪ�i��J(�i"�u�j��}9��z�j�͗R��+�5f|�^#����א}˒g�Ս����Hb݀�M��C�x����x/��9SU��P��!o›�q"^x��5��� �&[��;�lW�ve�Y�K̸�w[�֪�g�8�Ԭ��,$�)$�T����c���Z���f[��Z,�p���;� ���߿?$��|�OӺ��|r�eu?ޟ�QM��������4|{&�In��O=O��/�Ϗ�g��>�����_(�Ҿ��j���Z��>ź;�5�N�$p`$`|����S����1��xƇ��۰ۑ�"M]��p1s�u^������'4�M�9 �i�Z��j�%��`P����oY�fխ��2;��X����T@yh A theoretical study of chronopotentiometry and chronoamperometry at unshielded electrodes.
