C) Nickel (II) nitrite – Ni(NOO\u2082) a
D) Manganese(III) sulfite – Mn(SSO)<\/p>\n\n\n\n

The formula CrSO<\/strong> is incorrect because it doesn’t account for the correct stoichiometry of chromium and sulfate ions. The correct formula should be CrSO\u2084<\/strong>, where one chromium ion pairs with one sulfate ion to balance the charges. This combination results in a neutral compound.<\/p>\n","protected":false},"excerpt":{"rendered":" Which has the incorrect name-formula combination?A) Chromium(II) sulfate-CrSOB) Cobalt (III) nitrate – Co(NO),C) Nickel (II) nitrite – Ni(NOO\u2082) aD) Manganese(III) sulfite – Mn(SSO) The Correct Answer and Explanation is : Let’s go through each option to identify the incorrect name-formula combination: A) Chromium(II) sulfate – CrSOChromium(II) sulfate should contain chromium with a +2 charge (Cr\u00b2\u207a) […]<\/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-192516","post","type-post","status-publish","format-standard","hentry","category-exams-certification"],"_links":{"self":[{"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/posts\/192516","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=192516"}],"version-history":[{"count":0,"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/posts\/192516\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/media?parent=192516"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/categories?post=192516"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/tags?post=192516"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
Chromium(II) sulfate should contain chromium with a +2 charge (Cr\u00b2\u207a) and sulfate (SO\u2084\u00b2\u207b) ions. Therefore, the correct formula should be CrSO\u2084<\/strong> (one chromium ion for each sulfate ion). The formula CrSO<\/strong> is incorrect because it lacks the proper number of oxygen atoms for the sulfate ion.<\/p>\n\n\n\n
Cobalt(III) has a +3 charge (Co\u00b3\u207a), and nitrate (NO\u2083\u207b) has a -1 charge. To balance the charges, we need three nitrate ions for every cobalt ion. Therefore, the correct formula is Co(NO\u2083)\u2083<\/strong>, which matches the name provided.<\/p>\n\n\n\n
Nickel(II) has a +2 charge (Ni\u00b2\u207a), and nitrite (NO\u2082\u207b) has a -1 charge. To balance the charges, we need two nitrite ions for every nickel ion. The correct formula is Ni(NO\u2082)\u2082<\/strong>, which matches the name provided.<\/p>\n\n\n\n
Manganese(III) has a +3 charge (Mn\u00b3\u207a), and sulfite (SO\u2083\u00b2\u207b) has a -2 charge. The formula should balance the charges, which means we need two sulfite ions for every manganese ion. The correct formula should be Mn\u2082(SO\u2083)\u2083<\/strong>. The formula Mn(SSO)<\/strong> is incorrect because “SSO” is not a proper chemical notation, and it does not correctly represent sulfite ions.<\/p>\n\n\n\nCorrect Answer:<\/h3>\n\n\n\n
