In this paper, the method is applied to sodium carbonate (Na2CO3)and portassium carbonate (K2CO3) aqueous solutions in order to examine volume changes in diluting these solutions with water at 20℃ using their density data. The concentration ranges of original Na2CO3 and K2CO3 aqueous solutions are 0-0.1500 and 0-0.5000 mass fractions of solutes respectively. The volume ratios of the original aqueous solution to the added water are 1.000mL:9.000mL, 3.000mL:7.000mL, 5.000mL:5.000mL, 7.000mL:3.000mL, and 9.000mL:1.000mL. For both solutions, as the concentrations of the original solution are increasing, the values are decreasing, and their minimums are 9.959mL for the Na2CO3 aqueous solution and 9.753mL for the K2CO3 aqueous one at the ratio 5.000mL:5.000mL. The obvious volume decreases are recognized after diluting original solutions. Using this method, the VM alues can be simply estimated without performing experiments, and therefore it is useful as teaching material for high school science.","subitem_description_type":"Other"}]},"item_2_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.18878/00002039","subitem_identifier_reg_type":"JaLC"}]},"item_2_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00085725","subitem_source_identifier_type":"NCID"}]},"item_2_text_9":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"神戸女学院大学人間科学部環境・バイオサイエンス学科"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2014-12-01"}],"displaytype":"detail","filename":"KJ00009655759.pdf","filesize":[{"value":"525.3 kB"}],"format":"application/pdf","license_note":"神戸女学院大学研究所","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00009655759","url":"https://kobe-c.repo.nii.ac.jp/record/2078/files/KJ00009655759.pdf"},"version_id":"2398910c-bbe1-4f50-8975-25383bc6b9e6"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"二成分系水溶液","subitem_subject_scheme":"Other"},{"subitem_subject":"希釈","subitem_subject_scheme":"Other"},{"subitem_subject":"体積変化","subitem_subject_scheme":"Other"},{"subitem_subject":"マイクロスケール実験","subitem_subject_scheme":"Other"},{"subitem_subject":"炭酸ナトリウム","subitem_subject_scheme":"Other"},{"subitem_subject":"炭酸カリウム","subitem_subject_scheme":"Other"},{"subitem_subject":"binary aqueous solution","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"dilution","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"volume change","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"microscale experiment","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"sodium carbonate","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"potassium carbonate","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"二成分系水溶液の希釈に伴う体積変化に関する考察(4)-炭酸ナトリウム水溶液および炭酸カリウム水溶液-","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"二成分系水溶液の希釈に伴う体積変化に関する考察(4)-炭酸ナトリウム水溶液および炭酸カリウム水溶液-"},{"subitem_title":"Consideration on Volume Change in Diluting Binary Aqueous Solutions,Part 4-Aqueous Sodium Carbonate and Potassium Carbonate Solutions-","subitem_title_language":"en"}]},"item_type_id":"2","owner":"3","path":["274"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-12-01"},"publish_date":"2014-12-01","publish_status":"0","recid":"2078","relation_version_is_last":true,"title":["二成分系水溶液の希釈に伴う体積変化に関する考察(4)-炭酸ナトリウム水溶液および炭酸カリウム水溶液-"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-06-19T11:23:52.327209+00:00"}
