Balanced chemical equation?

Balanced chemical equation problem?

• Balanced chemical equation question? write a balanced chemical equation and answer the questions for the following 1.Aqueous sodium hydroxide is added to a saturated solution of aluminum hydroxide, forming a complex ion If the resulting mixture is acidified would the concentration of the complex ion increase, decrease, or remain the same? explain 2. Hydrogen chloride gas is oxidized by oxygen if three moles of hydrogen chloride gas and three moles of oxygen gas react as completely as possible which reactant if any is present in excess? Justify your answer 3. Solid potassium oxide is added to water If a few drops of phenolphthalein are added to the resulting solution, what would be observed? explain

• Answer:

  NaOH(aq) + AlOH = Decrease, since H and OH will get together turning into water. More water same quantity of complex= concentration decreasing! 3HCl(g) + 3O2= ClO2 + H2O + O2 + Cl- In excess, Cl. K2O + H2O= 2KOH Since KOH is a stong base, the phenolphthalein will get colourless.
