The net ionic equation for formation of an aqueous solution of Al(NO3)3 via mixing solid Al(OH)3 and aqueous nitric acid is __________.

Consider two solutions. One solution is 0.115 M Ca(OH)2. The other solution is 0.1050 M HNO3. a. Write a balanced equation for the reaction when the two solutions are mixed. b. How many mL of Ca(OH)2 will be required to neutralize 25 mL of HNO3

An unknown hydroxide of the formula X(OH)2 is only slightly soluble in water. A scientist is curious as to what hydroxide this is. So, she takes this hydroxide and dissolves enough of it in pure water to make a saturated solution. She then takes 25.00 mL of the saturated solution and titrates it with 0.000100 M HCl. She notes that it takes 2.58 mL of HCl to fully neutralize the saturated solution.  1. Determine the Ksp of the hydroxide. (concentration of X(OH)2  is 1.032 x 10-5 M, pH = 9.31, molar solubility should be 1.032 x 10-5 M)

List the ions and molecules that may have precipitated as part of your final salt product. Step 1. Dissolve the Aluminum metal : (adding solid Al to a Kott Solution) Peaction between Al metal and kot. AICOH and H₂ gas.. Net ionic equation: Solution produces Tetrahydroko aluminate ion 2 A1 (s) + 20H (aq) + 6 +₂0 (1) → 2 Al (OH) - (aq) + 3H2(g) K+(aq) OH(aq) equation that describes the reaction of Sulfuric acid in water: OR H₂SO4 (aq) + H₂0 (1) H₂O+ (aq) + Hs 04" (aq) 2- HSO4 (aq) + H₂O (1) H₂0+ (aq) + 504³ (aq) Step 3: Neutralize base with acid OH reacts with acid: H₂Ocaq) + OH(aq) → 2+1₂0 (1) • Al(OH), reacts with small amount of acid; Alcot)" (q) + Hy" O cag) Al(only (n+ H₂OCD Al(OH) reacts with large amount of acid (with heat): Al (DH), (s) + 3H₂ 0 (aq) → A1 " (aq) + 6 H₂0 (1)

A 25.00 mL aliquot is withdrawn from the liquid portion of saturated Manganese (II) hydroxide and transferred to an Erlenmeyer flask.  After the addition of methyl orange, a titration with 0.0045 M HCl was performed.  The endpoint was reached after 8.72 mL of the acid was added.   What is the balanced chemical equation? How many moles of hydroxide ions were neutralized in the reaction?  What is the molar concentration of hydroxide in the saturated solution?  What is the molar concentration of Magnesium ion in solution?

No Plagiarism Please! KOH + HBr → KBr + H2O A student sets up a titration apparatus with 25 mL of potassium hydroxide in the flask. In three to five sentences, explain how the student can use a 0.1 M solution of hydrobromic acid to determine the concentration of potassium hydroxide in the reaction.

Consider a gas-evolution reaction as below: CaCO3(s) + 2 HNO3(aq) ----> Ca(NO3)2(aq) + CO2(g) + H20(1) What is the net ionic equation in this reaction?

Classify each reaction as precipitation, acid-base, or no reaction. If the reaction is a precipitation, record either the Ksp or solubility of the product to determine if a precipitate is likely to be seen. Use a reference to see if the product formed may be colored or have an odor. If no reaction happens, write NR in the classification line.   Thank you!
