Molar mass is 56,11 g\/mol. The aqueous alkali has a density of approximately 1,028 g\/cm³ and a boiling point of about 100 °C. Packed as 500 ml in plastic, it is intended for volumetric standard work on the analytical bench. Potassium hydroxide solutions of defined concentration are used in acid–base titrations and related quantitative procedures that call for 0,5 mol\/l or 0,5 N KOH. This ROTI®Star volumetric solution from manufacturer Carl ROTH provides that concentration in a laboratory pack, so the alkali is already dissolved at 0,5 mol\/l. Analytical laboratories using volumetric standard solutions can employ the 500 ml plastic bottle wherever a 0,5 N potassium hydroxide solution is specified. Identification of the reagent rests on the formula KOH, the CAS number 1310-58-3 and the stated molar mass, density and boiling point of this aqueous preparation.\u003c\/p\u003e\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCAS number: 1310-58-3\u003c\/li\u003e\n\u003cli\u003ePack sizes: 500 ml, 1 l\u003c\/li\u003e\n\u003cli\u003eEG nr.: 215-181-3\u003c\/li\u003e\n\u003cli\u003eEmpirical formula: KOH\u003c\/li\u003e\n\u003cli\u003eDensity: ~1,028 g\/cm³\u003c\/li\u003e\n\u003cli\u003eUNSPSC: 12352305\u003c\/li\u003e\n\u003cli\u003eTechnical Information Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/www.carlroth.com\/medias\/SPEZ-28MK-EN.pdf?context=bWFzdGVyfHNwZWNpZmljYXRpb25zfDEwMzAwM3xhcHBsaWNhdGlvbi9wZGZ8YURSbUwyZzVNaTg1TWpnek5qZ3pNREkwT1RJMkwxTlFSVnBmTWpoTlMxOUZUaTV3WkdZfGQxODA5OGQ0ODQzOWY4YjNhYTU3MTkzNDhiZDM3NTBiMDBmMzgwMTFiZjU5MTNmNzZiN2ViNGU4NTc4MjAzZTc\" target=\"_blank\" rel=\"noopener noreferrer\" title=\"Technical sheet PDF\" aria-label=\"Technical sheet PDF\"\u003e\u003cimg class=\"sds-icon\" src=\"https:\/\/img.icons8.com\/color\/48\/pdf.png\" alt=\"PDF\" width=\"18\" height=\"18\" style=\"width:18px;height:18px;max-width:18px;margin:0;padding:0;display:inline-block;vertical-align:middle;border:0;\"\u003e\u003c\/a\u003e\n\u003c\/li\u003e\n\u003cli\u003eSafety Data Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/www.carlroth.com\/medias\/SDB-28MK-DE-EN.pdf?context=bWFzdGVyfHNlY3VyaXR5RGF0YXNoZWV0c3wzMTk3NjF8YXBwbGljYXRpb24vcGRmfGFHTTJMMmd6TWk4NU1qYzRPRFEyTmpNeE9UWTJMMU5FUWw4eU9FMUxYMFJGWDBWT0xuQmtaZ3xlMDc4OTM3MjViZGI5MmZkODNkOTNmMzY1ZTU1YWRmOWYzYTlkOWU2Y2U5ODExOTIzOWE1NWY4NzgxMzI1ZDY4\" target=\"_blank\" rel=\"noopener noreferrer\" title=\"SDS PDF\" aria-label=\"SDS PDF\"\u003e\u003cimg class=\"sds-icon\" src=\"https:\/\/img.icons8.com\/color\/48\/pdf.png\" alt=\"PDF\" width=\"18\" height=\"18\" style=\"width:18px;height:18px;max-width:18px;margin:0;padding:0;display:inline-block;vertical-align:middle;border:0;\"\u003e\u003c\/a\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Luminix Health","offers":[{"title":"500 ml","offer_id":58656460833100,"sku":"28MK.1","price":106.45,"currency_code":"EUR","in_stock":true},{"title":"1 l","offer_id":58656460865868,"sku":"28MK.2","price":170.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/28MK-1.jpg?v=1788331353","url":"https:\/\/www.luminixhealth.com\/de-be\/products\/potassium-hydroxide-solution-roti-star-0-5-mol-l-0-5-n-500-ml-28mk","provider":"Luminix Health","version":"1.0","type":"link"}
