The conditions for the complete decomposition of potassium borofluoride are: (1) initial concentration of acid; 0.02N HCl, (2) concentration of calcium chloride; 1M, (3) total volume of aqueous solution; 100ml, (4) time of boiling; 5 minutes. The amount of hydrochloric acid previously added is subtracted from titration, thus less than about 250mg sample can be determined. When more than 250mg sample is treated, the decomposition is incomplete because the concentration of the liberated acid exceeds the suitable range for 15 the decomposition. Then, after the first decomposition and titration, the conditions are adjusted again and the second decomposition and titration is continued, thus more than 1000mg sample can be determined.", "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_31": {"attribute_name": "フォーマット：mimeタイプ", "attribute_value_mlt": [{"subitem_description": "application/pdf", "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 2: 9-15(1968)", "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_select_64": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "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_39": {"attribute_name": "NII 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_10_text_66": {"attribute_name": "sortkey", "attribute_value_mlt": [{"subitem_text_value": "03"}]}, "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": [{"nameIdentifier": "49535", "nameIdentifierScheme": "WEKO"}]}]}, "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", "download_preview_message": "", "file_order": 0, "filename": "Liberal_arts_S02-03.pdf", "filesize": [{"value": "329.9 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_note", "mimetype": "application/pdf", "size": 329900.0, "url": {"label": "Liberal_arts_S02-03.pdf", "url": "https://soar-ir.repo.nii.ac.jp/record/17647/files/Liberal_arts_S02-03.pdf"}, "version_id": "1aadc322-c6f3-4d59-be2f-8b4cc8635eca"}]}, "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": "ホウフッ化カリウムの中和滴定", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "ホウフッ化カリウムの中和滴定", "subitem_title_language": "ja"}, {"subitem_title": "Acidimetric determination of potassium borofluoride.", "subitem_title_language": "en"}]}, "item_type_id": "10", "owner": "1", "path": ["1729"], "permalink_uri": "http://hdl.handle.net/10091/4292", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2010-02-12"}, "publish_date": "2010-02-12", "publish_status": "0", "recid": "17647", "relation": {}, "relation_version_is_last": true, "title": ["ホウフッ化カリウムの中和滴定"], "weko_shared_id": -1}
