WebMay 31, 2024 · HCl, HBr, and HI are all strong acids, whereas HF is a weak acid. Why HF is a weak acid class 12? Hydrofluoric acid (HF) is not a strong acid but instead a weak acid. It is classified as a weak acid mainly because it fails to completely dissociate in water. … A vast amount of energy is required to break the powerful H-F bond in water. WebJun 26, 2024 · H Cl is a strong acid, while H F is a weak acid. Explanation: Acid strength refers to how much an acid ionizes when dissolved in water. In Arrhenius acid-base theory, an acid is a substance which dissolves in water to release one or more H + ions. A strong acid ionizes completely when dissolved in water.
Why is HF acid so reactive, and why does sand dissolve in it rather ...
WebJan 30, 2024 · From a table of molar masses, such as a periodic table, we can calculate the molar mass of NaF to be equal to 41.99 g/mol.

HCl is a stronger acid because the bond between H and Cl is weaker than the bond between H and F (this is because Cl has a greater atomic radius). HClO is a stronger acid than HBrO because the resulting anion of HClO is more stable as a result of Cl having … softgalaxy technologies inc

WebDec 3, 2024 · HF is a weak acid because it doesn't completely dissociate when mixed with water. Here's the equation when HF reacts with water: HF + H2O --> H3O (+) + F-. That … WebOct 29, 2024 · The difference is that a strong electrolyte dissociates completely in water, while a weak electrolyte partly dissociates. For instance, hydrochloric acid (HCl) and hydrofluoric acid (HF) dissociate in water to produce H + ( these reactive H+ ions share a lone pair of electrons on the oxygen atom of water (H2O) to form the hydronium ion, H3O+.
