large. It would be considered to generally be a strong acid considering that it has one less oxygen than a strong acid like perchlorate (HCLO4). In above reaction water act as base and by the help of lone pair of electron of oxygen it attract proton from acid HNO2. At equilibrium, the concentrations of The pH of a weak acid should be less than 7 (not neutral) and it's usually less than the value for a strong acid. It is also a highly polar compound. Strong acids have high Ka or small pKa values, weak acids have very small Ka values or large pKa values. So, HNO2 donates the proton to the H2O molecule and itself forms a conjugate base which is NO2.

A weak acid is any acid that is not one of the seven strong (e.g., H3PO4, HNO2, H2SO3, HClO, HClO2, HF, H2S, HC2H3O2, and so on). HNO2 (aq) dissolves in aqueous solution to form H+ (aq) and NO2 (aq). . This is significant because the electrons can delocalize over a greater volume that allows for more stabilization of the negative charge. Expert Answer. Weak acids have a higher pH value at the same concentration as strongacids. As a result, when we examine the carbonicacid H2CO3, it will be a strong and resonance staballized base CO3 after losing a proton, H. As a result, its a weak acid. Or a substance is said to be acid when it increases the concentration of H+ion in solution and a substance is said to be base when it increases the concentration of OHin solution. That can become acute when left untreated. https://www.thoughtco.com/list-of-strong-and-weak-acids-603642 (accessed March 4, 2023).

Aweak acid is any acid that is not one of the seven strong (e.g. KOH is a salt because it is made up of inorganic compounds and forms a solid without any solvent. When we compare the conjugate base formed by two acid of nitrogen the result will be just reverse of acidity. Strong and weak acids are important to know both for chemistry class and for use in the lab. Solution for A weak acid is added to a solution of strong acid (HCl) of unknown concentration. it is a strong or weak acid. If the bond is more polar electronegativity difference is increased and bond electron is more attracted by more electronegative atom which make easy to dissociate H, Lewis theory of acid; according to this theory acid is a compound which has at least one vacant orbital to accept pair of electron from base. Completely dissociates in aqueous solution. When a weak acid and a weak base are mixed, they come to an equilibrium state represented by the following equation: HA(aq) + B(aq) Answered: Each of the following pairs contains Conjugate Acid-Base Pairs, Strong and Weak Acids and Bases It signifies only that the acid contains an H+ ion that isn't present in the conjugate base.
