Ph of nh4br
The salt of strong acid and strong base are neutral having pH = 7. The salts of a weak acid and strong base are basic having pH > 7. The salts of strong acid and weak base are acidic having pH < 7. In the case of NH4Br, Hydrogen Bromide is a strong acid while Ammonia is a weak base. Visa mer We know that a reaction between an acid and a base is known as the neutralization reaction and the end-product formed in such reactions is known as the salt. The salt so formed … Visa mer The substances that give away their proton when dissolved in an aqueous solution are termed acids. Acids are usually sour in taste … Visa mer Several theories provide us with the definition of the base. Three of the important ones define base as follows: Lewis theory: A molecule that has an unshared pair of … Visa mer The pH of a solution determines its acidity or basicity. The pH value for any substance ranges from 1 to 14 on the pH scale where pH 7 is neutral (it is the pH of water). If the pH value of a substance is below 7, it is … Visa mer Webb15 juli 2024 · NH4Br is an acidic salt (from a strong acid and a weak base), so the pH should be <7. Is NH4Br soluble or insoluble in water? Ammonium bromide, NH4Br, is the ammonium salt of hydrobromic acid. The chemical crystallizes in colorless prisms, possessing a saline taste; it sublimes on heating and is easily soluble in water.

Ammonium bromide, NH4Br, is the ammonium salt of hydrobromic acid. The chemical crystallizes in colorless prisms, possessing a saline taste; it sublimes on heating and is easily soluble in water. On exposure to air it gradually assumes a yellow color because of the oxidation of traces of bromide (Br ) to bromine (Br2).
