    • A strong acid/base titration goes to completion the instant we add the solution. —A weak acid/base titration reacts and than reestablishes equilibrium. Therefore, we need to do two steps upon the introduction of a strong acid/base to a weak acid/base equilibrium: 1. React the strong acid or base to completion with the weak acid/base of interest.
    • In contrast to strong acids and bases, the shape of the titration curve for a weak acid or a weak base depends dramatically on the identity of the acid The number of millimoles of OH− equals the number of millimoles of CH3CO2H, so neither species is present in excess.
    • H2CO3 is a weak acid and does not completely dissociate. HCO3- will act as a base by plucking off the proton from H2O, and forming a basic solution. Strong acids and bases have a high Ka and Kb value and so their equilibriums lie far towards the product side.

I KNOW that H2SO3 is an acid which rules out options a & c; however, I am not certain if it is a weak or strong acid. Note, that for a very weak acids - when K a approaches 0 - numerator also approaches zero and result of pH calculation can be higher than 7. For example using pK a =14 and C a =0.01 M we get pH=8. That's the effect of neglecting water dissociation, similar to the one observed when we used equation 7.6 for strong acids.

    Mar 19, 2018 · For Ag2SO4 adding H+ forms HSO4- and that is k2 for H2SO4, there is no k1 since H2SO4 is a strong acid for the first H. so YES more soluble in acid than in water. For BaSO3 adding H+ forms HSO3- and that is k2 for H2SO3 , there is no k1 since H2SO3 is a strong acid for the first H. so YES more soluble in acid than in water. SrSO4 would be HSO4^- Weak acids and weak bases. A weak acid is a proton donor that when put in water will only partially dissociate.

    The terms weak and strong are used to compare the strengths of acids and bases The terms dilute and concentrated are used to compare the concentration of solutions They do not mean the same thing! The combination of strength and concentration determines the behavior of the acid or base. Ammonia, NH3, is a weak base; the other compounds are salts. You can decide the acidity or basicity of salt solutions by noting whether the corresponding acid and base are strong or weak. For example, NH4Br is the salt of a weak base (NH3) and a strong acid (HBr), so the salt is acidic. Strong acids/bases give rise to weak conjugate bases/acids.
