Write a net ionic equation to show why solid barium hydroxide, Ba(OH)2 (s), forms a basic solution when it dissolves in water.

Aluminum sulfate, known as cake alum, has a remarkably wide range of uses, from dyeing leather and cloth to purifying sewage. In aqueous solution, it reacts with base to form a white precipitate. (a) Write balanced total and net ionic equations for its reaction with aqueous NaOH. (Type your answer using the format (NH4)2CO3 for (NH4)2CO3, [NH4]+ for NH4+, and [Ni(CN)4]2- for Ni(CN)42-. Use the lowest possible coefficients. Type the cation before the anion.)overall equation  (aq) +  NaOH(aq)    (aq) +   (s)net ionic  (aq) +   (aq)    (s)(b) What mass of precipitate forms when 104.5 mL of 0.616 M NaOH is added to 517 mL of a solution that contains 18.4 g aluminum sulfate per liter?  g

Write the balanced net ionic equation including heat in the equation. The reaction is exothermic.

A chemistry student weighs out 0.159 g of ascorbic acid (H,C,H,0), a diprotic acid, into a 250. mL volumetric flask and dilutes to the mark with distilled water. He plans to titrate the acid with 0.0800M NaOH solution. Calculate the volume of NaOH solution the student will need to add to reach the final equivalence point. Be sure your answer has the correct number of significant digits. mL
