Eriochrome Black<\/b> T is a complexometric indicator commonly employed in tests for water hardness, particularly during EDTA titrations. It transitions from wine-red to blue as it binds and subsequently releases metal ions such as calcium and magnesium, facilitating the determination of their concentration in a solution.<\/p>\n","protected":false},"featured_media":0,"template":"","meta":{"content-type":""},"product_brand":[],"product_cat":[33530],"product_tag":[28672,51722],"class_list":["post-92106","product","type-product","status-publish","product_cat-powders-dyes","product_tag-eriochrome-black-t-acs-reagent","product_tag-99-0","first","instock","taxable","shipping-taxable","purchasable","product-type-simple"],"_links":{"self":[{"href":"https:\/\/safetyboot4u.co.za\/index.php?rest_route=\/wp\/v2\/product\/92106","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/safetyboot4u.co.za\/index.php?rest_route=\/wp\/v2\/product"}],"about":[{"href":"https:\/\/safetyboot4u.co.za\/index.php?rest_route=\/wp\/v2\/types\/product"}],"wp:attachment":[{"href":"https:\/\/safetyboot4u.co.za\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=92106"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/safetyboot4u.co.za\/index.php?rest_route=%2Fwp%2Fv2%2Fproduct_brand&post=92106"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/safetyboot4u.co.za\/index.php?rest_route=%2Fwp%2Fv2%2Fproduct_cat&post=92106"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/safetyboot4u.co.za\/index.php?rest_route=%2Fwp%2Fv2%2Fproduct_tag&post=92106"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
