How to solve ions
WebWhen we break this up into its ions, we get H2 (aq) + SO4 (2−) (aq) + 2 Na+ (aq) + 2 OH− (aq) → 2 Na+ = SO4 (2−) (aq) + 2 H2O (ℓ). So we can "cancel" the 2 Na+ (aq) and the SO4 (2−) (aq) on each side. Okay. Then the resulting reaction is H2 (aq) + 2 OH− (aq) → 2 H2O (ℓ). WebFeb 9, 2024 · First, we need to write out the two equations. AgBr (s) ⇌ A g + (aq) + B r ¯ (aq) K s p = [ A g +] [ B r ¯] Now, since in this problem we're solving for an actual value of K s p, we plug in the solubility values we …

WebFeb 24, 2024 · The pH scale ranges from 0 to 14 under usual conditions and measures the acidity of an aqueous solution. This is derived from the molarity of protons (hydrogen ions, or H+) in the solution. To find pH for a given molarity, you need to know how to work with logarithmic equations and a pH formula.
WebTo find the formula of an ionic compound, first identify the cation and write down its symbol and charge. Then, identify the anion and write down its symbol and charge.
