Thermo Scientific™ Orion™ Silver/Sulfide Electrodes have dual electrode measuring silver and sulfide ions in aqueous solutions and perform low-level cyanide and halide titrations. Ion Electrolyte B Reference filling solution is supplied with the electrode and can be used for most silver or sulfide measurements and titrations. When silver sulfide is formed on electrical contacts operating at atmosphere rich in hydrogen sulfide, it results to the formation of long filaments known as silver whiskers. x�b```b``d`e`�� ̀ �@1V�&6�L 3z�Ҍ\ɭ�B�����x�h��qt@ 0M(F2@�Pb�a��`����Y,����,~�k,|�k��[�J��gc`U�d ;����X�-Av�z� %\� endstream endobj 12 0 obj<>/Metadata 9 0 R/Pages 8 0 R/Type/Catalog/PageLabels 6 0 R>> endobj 13 0 obj<>/Font<>/ProcSet[/PDF/Text]/ExtGState<>>>/Type/Page>> endobj 14 0 obj<> endobj 15 0 obj<> endobj 16 0 obj<> endobj 17 0 obj[/ICCBased 30 0 R] endobj 18 0 obj<> endobj 19 0 obj<>stream 11 0 obj <> endobj xref 11 22 0000000016 00000 n ��:xwC]���6����j�g�tVmC�t�|�[�u_��ǖ�i澰���T�n��M?=7ÙW*xs ��^��W^�tP^��{����,� �*�_���YKغh�}7��>�O�yY�����C��X��*{a�n�����L�m��G!��m�]9��"�l��� >�G��'L#�#�G[�V8��18N�����#6���X4���� g"9� ��L�C���!�j ����$?���E�E98FH�@�I} �AmFj3�5�k�k���׈���__ȀQ��ҏ=����X�n��L���X�q���W� 0000003779 00000 n pH, Ion Conductivity, & Oxygen Measurement Make quick, simple, accurate and economical measurements of silver and sulfide ions in aqueous solutions. 0000010232 00000 n Most metal sulfate compounds are readily soluble in water for uses such as water treatment, unlike fluorides and oxides which tend to be insoluble. This effect, typical of semiconductors, is the opposite of that measured in metals such as copper, where conductivity decreases as temperature is increased. 0000000960 00000 n We use cookies to enhance your experience. Silver sulfide electrodes respond to both silver and sulfide ions with good practical detection limits (10 −8 –10 −7 mol l −1) in Nernstian manner.

The company has helped develop a natural fiber composite racing seat, echoing the racing and automotive industry's move towards more sustainable technologies. When silver sulfide is formed on electrical contacts operating at atmosphere rich in hydrogen sulfide, it results to the formation of long filaments known as silver whiskers. The enhancement in conductivity could result from structural change of Ag2S film. While investigating the effect of temperature on "sulphurette of silver" (silver sulfide) in 1833 he found that electrical conductivity increased with increasing temperature. very unlikely to play any role on the conductivity of Ag2S film.
