The correct answer and Explanation is :<\/strong><\/mark><\/p>\n\n\n\n The most likely pH of a solution containing many hydroxide ions (OH\u207b) and few hydrogen ions (H\u207a) is:<\/p>\n\n\n\n D. 9<\/strong><\/p>\n\n\n\n The pH scale measures the concentration of hydrogen ions (H\u207a) in a solution. It ranges from 0 to 14, with 7 being neutral. A pH less than 7 indicates an acidic solution, where there is a higher concentration of hydrogen ions compared to hydroxide ions. Conversely, a pH greater than 7 indicates a basic (or alkaline) solution, where there is a higher concentration of hydroxide ions compared to hydrogen ions.<\/p>\n\n\n\n In a basic solution, the concentration of hydroxide ions (OH\u207b) is higher relative to hydrogen ions (H\u207a). This is because the pH of a solution is inversely related to the concentration of hydrogen ions. Specifically, the pH is calculated as:<\/p>\n\n\n\n [ \\text{pH} = -\\log[\\text{H}^+] ]<\/p>\n\n\n\n where ([\\text{H}^+]) is the concentration of hydrogen ions. For basic solutions, the pH will be greater than 7.<\/p>\n\n\n\n The relationship between the pH and pOH (the concentration of hydroxide ions) is given by the equation:<\/p>\n\n\n\n [ \\text{pH} + \\text{pOH} = 14 ]<\/p>\n\n\n\n For a solution with a pH of 9, the pOH can be calculated as:<\/p>\n\n\n\n [ \\text{pOH} = 14 – \\text{pH} ] This indicates that the concentration of hydroxide ions is relatively high compared to the concentration of hydrogen ions, confirming that the solution is basic.<\/p>\n\n\n\n In summary, a solution with many hydroxide ions and few hydrogen ions will have a pH greater than 7. Among the given options, a pH of 9 is the most appropriate choice for such a solution.<\/p>\n","protected":false},"excerpt":{"rendered":" What is most likely the pH of a solution containing many hydroxide ions (OH-) and few hydrogen ions(H+) A.2 B.6 C.7 D.9 The correct answer and Explanation is : The most likely pH of a solution containing many hydroxide ions (OH\u207b) and few hydrogen ions (H\u207a) is: D. 9 Explanation: The pH scale measures the […]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"footnotes":""},"categories":[25],"tags":[],"class_list":["post-137491","post","type-post","status-publish","format-standard","hentry","category-exams-certification"],"_links":{"self":[{"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/posts\/137491","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/comments?post=137491"}],"version-history":[{"count":0,"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/posts\/137491\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/media?parent=137491"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/categories?post=137491"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/tags?post=137491"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}Explanation:<\/h3>\n\n\n\n
