It lists common materials ranging from highly acidic substances like battery acid and gastric acid to neutral substances like water, and highly alkaline substances such as drain cleaner and bleach. The scale is presented clearly, with numerical values ranging from 1 to 14, illustrating the progression from increasingly acidic conditions through neutral points up to increasingly alkaline environments. This educational resource serves as a quick reference guide for understanding chemical properties in laboratory or academic settings, emphasizing the correlation between pH levels and indicator colors to facilitate accurate substance classification and safety assessments. By visualizing the pH spectrum, users can easily determine the chemical nature of common household and biological liquids, aiding in experiments involving acid-base neutralization or environmental testing and safety awareness.",{"@graph":14,"@context":73},[15,34,56],{"@type":16,"itemListElement":17},"BreadcrumbList",[18,23,27,31],{"item":19,"name":20,"@type":21,"position":22},"https://docshare.wps.com","Home","ListItem",1,{"item":24,"name":25,"@type":21,"position":26},"https://docshare.wps.com/template/","Template",2,{"item":28,"name":29,"@type":21,"position":30},"https://docshare.wps.com/template/general/","General",3,{"item":32,"name":10,"@type":21,"position":33},"https://docshare.wps.com/template/ph-scale-universal-indicator-colours/563628/",4,{"url":32,"name":10,"@type":35,"image":36,"author":41,"headline":10,"publisher":44,"fileFormat":47,"inLanguage":8,"description":12,"dateModified":48,"datePublished":49,"encodingFormat":47,"isAccessibleForFree":50,"interactionStatistic":51},"DigitalDocument",{"url":37,"@type":38,"width":39,"height":40},"https://docshare.wps.com/thumbnails/ph-scale-universal-indicator-colours/563628.png","ImageObject",442,249,{"name":42,"@type":43},"Connor
