Below 5℃, potassium is quantitatively precipitated in the solution containing anyone of the the tert-butyl alcohol, iso-propyl alcohoL or ethyl alcohol in the concentration of 70%, and 0.2N hydrochloric acid, when the tetrafluoroboric acid is added to the concentration of about 5%, In this case the tetrafluoroboric acid must contain a small excess of the free hydrofluoric acid, This precipitate is filtered and may be decomposed and titrated easily by the process established befor. When the tert-butyl alcohol is used, sodium does not interfere even if its quantity is equal to potassium.","subitem_description_type":"Abstract"}]},"item_10_description_30":{"attribute_name":"資源タイプ（コンテンツの種類）","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_10_description_5":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"信州大学教養部紀要. 第二部, 自然科学 4: 17-25(1970)","subitem_description_type":"Other"}]},"item_10_publisher_4":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"信州大学教養部"}]},"item_10_source_id_35":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0583-0613","subitem_source_identifier_type":"ISSN"}]},"item_10_source_id_40":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN0012116X","subitem_source_identifier_type":"NCID"}]},"item_1627890569677":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"原,  信"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2015-09-28"}],"displaytype":"detail","filename":"Liberal_arts_S04-02.pdf","filesize":[{"value":"407.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Liberal_arts_S04-02.pdf","url":"https://soar-ir.repo.nii.ac.jp/record/17631/files/Liberal_arts_S04-02.pdf"},"version_id":"5cf6708c-686c-413b-8317-842ae7f155f3"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"フルオロホウ酸塩中和滴定法によるカリウムの定量","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"フルオロホウ酸塩中和滴定法によるカリウムの定量","subitem_title_language":"ja"},{"subitem_title":"Determination of potassium by the acidimetric titration of its tetrafluoroborate","subitem_title_language":"en"}]},"item_type_id":"10","owner":"1","path":["1727"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2010-02-12"},"publish_date":"2010-02-12","publish_status":"0","recid":"17631","relation_version_is_last":true,"title":["フルオロホウ酸塩中和滴定法によるカリウムの定量"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-03-31T05:38:09.317895+00:00"}
