write the net equation for reaction of sulfate ion with Ba(NO3)2

"In the process of lime softening, calcium hydroxide (Ca(OH)2) is added to hard water to remove dissolved calcium, thereby 'softening' the water. How is it possible that adding calcium hydroxide to hard water can result in a net reduction in the concentration of Ca2+ ions? Explain."

Is Mg(OH)2 a acid, base, or neither?

Write the net ionic equation for the hydrolysis reaction that occurs when sodium acetate, NaCH3CO2, is dissolved in water (Hint: the equation should predict whether this salt is acidic, nuetral or basic).

7. Explain the following statements: HCIO3 is a stronger acid than HBRO3 b. A Ca(OH)2 solution will give a higher pH compared to a KOH solution at the same concentration and temperature. (Assume both substances are completely dissolved). a.

The hypochlorite ion is the conjugate base of the weak acid hypochlorous acid. The value of K₁ for CIO, is 2.86×10-7. Write the equation for the reaction that goes with this equilibrium constant. +

Describe in words how you do the following preparation. Then give molecular equation for the preparation. NaNO3(s) from Na2SO3(s)

Write the mass balance equation for a solution of saturated lithium fluoide which has a pH of 5.50. -O [Li*]+ [H3Oʻ] = [F] + [HF] + [OH] %3D O 2*[Li*] = [F] + [HF] %3D O [Lit] = [F] + [HF] %3D O [Li*] = [F]

Write the balanced equation that accounts for the source of OH- used in the following reactions: [Al(H2O)6]3+(aq) + 3 OH-(aq) = Al(OH)3(s) + 6 H2O(l) [FeCl4]-(aq) + 3 OH-(aq) = Fe(OH)3(s) + 4 Cl-(aq)

Write the balanced ionization reaction for Ca(OH)2
