It is characterized by its ability to change color from yellow to red and then to violet depending on the pH of the medium (transition range 6.8\u20138.2). It is typically prepared at low concentrations in distilled water and can be incorporated into culture media to monitor microbial activity or metabolic changes. It is a stable, low-toxicity compound when stored under proper conditions, protected from light and kept in airtight containers.  <\/p>\n","protected":false},"excerpt":{"rendered":"<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-658\" src=\"https:\/\/salvak.com.co\/wp-content\/uploads\/2026\/01\/Check.svg\" alt=\"\" width=\"24\" height=\"24\"> pH indicator in acid\u2013base titrations<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-658\" src=\"https:\/\/salvak.com.co\/wp-content\/uploads\/2026\/01\/Check.svg\" alt=\"\" width=\"24\" height=\"24\"> Microbiological culture media, such as those used for carbohydrate fermentation<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-658\" src=\"https:\/\/salvak.com.co\/wp-content\/uploads\/2026\/01\/Check.svg\" alt=\"\" width=\"24\" height=\"24\"> Cell culture, where it acts as a marker of pH changes in the medium<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-658\" src=\"https:\/\/salvak.com.co\/wp-content\/uploads\/2026\/01\/Check.svg\" alt=\"\" width=\"24\" height=\"24\"> Laboratory assays requiring visual monitoring of solution acidity or alkalinity<\/p>\n","protected":false},"featured_media":2034,"comment_status":"open","ping_status":"closed","template":"","meta":{"_joinchat":[]},"product_brand":[],"product_cat":[78],"product_tag":[],"class_list":{"0":"post-2184","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-physicochemical-line","8":"first","9":"instock","10":"shipping-taxable","11":"product-type-variable"},"_links":{"self":[{"href":"https:\/\/salvak.com.co\/en\/wp-json\/wp\/v2\/product\/2184","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/salvak.com.co\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/salvak.com.co\/en\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/salvak.com.co\/en\/wp-json\/wp\/v2\/comments?post=2184"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/salvak.com.co\/en\/wp-json\/wp\/v2\/media\/2034"}],"wp:attachment":[{"href":"https:\/\/salvak.com.co\/en\/wp-json\/wp\/v2\/media?parent=2184"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/salvak.com.co\/en\/wp-json\/wp\/v2\/product_brand?post=2184"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/salvak.com.co\/en\/wp-json\/wp\/v2\/product_cat?post=2184"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/salvak.com.co\/en\/wp-json\/wp\/v2\/product_tag?post=2184"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
