Question

1-give the formula for the acid conjugate to each of the following bases NH3 and OH?

2-1-give the formula for the acid conjugate to each of the following bases NH3 and HCO3- ?

================================================

For each of the following salts,indicate the weather it would form an acidic, a basic , or a neutral solution;

KC2H3O2

NaNO3

NH4Cl

NaF

=====================================

Limewater is a saturated solution of calcium hydroxide. What is the concentration(molarity) of a solution of limewater if a 25.0 mL sample requires 27.8mL of 0.225 M hydrochloric acid for complete neutralization ?

Explanation / Answer

1) conjugate acid-base pairs differ by only 1 H+
If NH3 is the base, then the conjugate acid is NH4+

2) The conjugate acid is H2O

NaNO3. Na+ is a conjugate acid of NaOH, a strong base. NO3- is the conjugate base of HNO3 (nitric acid), a strong acid. They will be about equal in strength, so the solution will be neutral

NH4Cl, ammonium chloride, is acutally mildly acidic when dissolved in water

NaF forms basic solition
