Which of the following is the strongest acid h3po4. The strength of an acid is determined by its Ka (acid dissociation constant) value, with a lower Ka indicating a stronger acid. . HCl There are 4 steps to solve this one. To understand the ranking, we need to consider the strength of acids in terms of their ability to dissociate into ions in an aqueous solution. In which of the following pairings of compounds are both members of the pair strong electrolytes? A) NaCN and KF B) NH3 and HBr C) KBr and H2CO3 D) NaBr and HBr a Determining the concentration of an acid using an acid-base titration always involves completely reacting a measured volume of the acid with a known volume of A) base of known Dec 23, 2024 · To determine the acidic strength of H3PO4, H3PO3, and H3PO2, we need to consider the structure and the number of hydrogen atoms that can dissociate. 7. H2CO3 - This is a weak acid. HC Step 1/2a. NH4+ - This is a weak acid. A common question is whether it behaves as a strong or weak acid. HC - This is not a valid chemical formula. We would like to show you a description here but the site won’t allow us. Sep 13, 2023 · The correct ranking of the given acids from strongest to weakest is: HCl > H2SO4 > HNO3 > H3PO4 > H2CO3 > CH3COOH. Acids are substances that donate protons (H+ ions) in solution. Simple to use laboratory reference chart for scientists, researchers and lab technicians. Acid and base chart lists the strength of acids and bases (strongest to weakest) in order. NaOH - This is a strong base, not an acid. Explanation: Acidity is determined by the ability of a substance to donate protons (H⁺ ions) in solution. e. CH3COOH The conjugate acid of a base, you add a H+ to the base. Strong acids have high Ka Table of Acid and Base Strength Which of the following is the strongest acid? H3PO4 NaOH H2CO3 NH4+ HCl Question: 15. c. PO43- Which of the following is not a strong acid? f A) HNO3 B) HC2H3O2 C) HClO4 D) HCl (aq) Question: Which of the following is the strongest acid? -H3PO4 -NH4+ -NaOH -H2CO3 -HCl Which of the following is the strongest acid? -H3PO4 -NH4+ -NaOH -H2CO3 -HCl There are 2 steps to solve this one. Which of the following is the strongest acid? A) H3PO4 B) NH4+ C) NaOH D) H2CO3 E) HCl HCl Which of the following is the strongest acid? H3PO4 NaOH H2CO3 NH4+ HCl B. Compare the acids based on their structures and electronegativity. H3PO4 - This is a weak acid. We need more information or options to determine the strongest acid. NaOH d. Stronger acids donate protons more readily. Which of the following is the conjugate acid of PO43- A. d. H2CO3 e. Phosphoric acid is a tribasic acid, meaning it has three dissociable hydrogen ions (H+) per molecule. Mar 26, 2025 · Which of the following is the strongest acid? A) H3PO4 B) NH4+ C) NaOH D) H2CO3 E) HCl The correct answer and explanation is : The correct answer is E) HCl (Hydrochloric acid). AnswerTherefore, none of the options given is the strongest acid. H3PO4 (phosphoric acid) is the strongest acid among the three because it can donate three protons (H+ ions), while H3PO3 (phosphorous acid) can donate two protons, and H3PO2 (hypophosphorous acid Aug 29, 2025 · Phosphoric acid (H3PO4) is a compound found in many everyday products, from food to industrial processes. NaOH c. 6) Which of the following is the strongest acid? a. HPO42- D. b. However, not all of these hydrogen ions dissociate completely in water, which affects its classification as an acid. HCl Which of the following is the strongest acid? a. From the given options, the acids are H3PO4, NH4+, and H2CO3. H2PO4- C. H3PO4 B. Here's the Question: Which of the following is the strongest acid? a. NH4 + c. Chemistry 101 Notes General Chemistry CHEM 142 Chemistry In Our Jan 25, 2026 · In this titration problem, we are given the volume and molarity of KOH (a strong base) used to titrate a sample of phosphoric acid (H3PO4), which is a triprotic acid (can donate 3 protons). NH4+ d. Feb 9, 2025 · The classification of H3PO4, or phosphoric acid, as a strong or weak acid is a matter of its chemical properties and behavior in aqueous solutions. Recall that the strength of an acid is determined by its ability to donate protons. This strength is measured using the acid dissociation constant (Ka) or pKa values.
