How can you determine whether an equation is endothermic or exothermic? The leveling effect applies to solutions of strong bases as well: In aqueous solution, any base stronger than OH is leveled to the strength of OH because OH is the strongest base that can exist in equilibrium with water. Predict whether the equilibrium for each reaction lies to the left or the right as written. This result clearly tells us that HI is a stronger acid than \(HNO_3\). Sulfuric acid is a colourless oily liquid. This compound liberates corrosive, toxic and irritating gases. In order to balance H2SO3 = H2O + SO2 you'll need to watch out for two things. The solubility of SO2 and the dissociation of H2SO3 in NaCl solutions.

The equilibrium constant is a way to measure what percentage of each acid is in the dissociated state (products) versus the associated state (reactant). In its molten form, it can cause severe burns to the eyes and skin. What is the formula mass of sulfuric acid?

It only takes a minute to sign up. Write a net ionic equation for the reaction that occurs, when ammonium carbonate (aq) and excess hydroiodic acid are combined.
