- Write molecular and net ionic equations for the successive neutralizations of each acidic hydrogen of sulfurous acid by aqueous calcium hydroxide. CaSO3 is insoluble; the acid salt is soluble.arrow_forwardWrite a net ionic equation for any precipitation reaction that occurs when 1 M solutions of the following are mixed. (a) copper(II) sulfate and sodium chloride (b) manganese(II) nitrate and ammonium hydroxide (c) silver nitrate and hydrochloric acid (d) nickel(II) sulfate and potassium hydroxide (e) ammonium carbonate and sodium nitratearrow_forwardssume a highly magnified view of a solution of HCI that allows you to “see” the HCl. Draw this magnified view. If you dropped in a piece of magnesium, the magnesium would disappear, and hydrogen gas would he released. Represent this change using symbols for the elements, and write the balanced equation.arrow_forward
- Give an example of a polyprotic acid and write equations for the successive neutralizations of the acidic hydrogen atoms of the acid molecule to produce a series of salts.arrow_forwardVitamin C has the formula C6H8O6. Besides being an acid, it is a reducing agent. One method for determining the amount of vitamin C in a sample is to titrate it with a solution of bromine, Br2, an oxidizing agent. C6H8O6(aq) + Br2(aq) 2 HBr(aq) + C6H6O6(aq) A 1.00-g "chewable" vitamin C tablet requires 27.85 ml of 0.102 M Br2 for titration to the equivalence point. What is the mass of vitamin C in the tablet?arrow_forwardFollow the directions of Question 7 for solutions of the following: (a) silver nitrate and sodium chloride (b) cobalt(II) nitrate and sodium hydroxide (c) ammonium phosphate and potassium hydroxide (d) copper(II) sulfate and sodium carbonate (e) lithium sulfate and barium hydroxidearrow_forward
- 3.85 The particulate drawing shown represents an aqueous so- lution of an acid HA, where A might represent an atom or group of atoms. Is HA a strong acid or a weak acid? Explain how you can tell from the picture.arrow_forwardThe pungent odor of vinegar is a result of the presence of acetic acid, CH3COOH. Only one hydrogen atom of the CH3COOH reacts with a base in a neutralization reaction. What is the concentration of acetic acid if a 10.00-mL sample is neutralized by 3.32 mL of 0.0100 M strontium hydroxide?arrow_forwardComplete and balance each of the following molecular equations (in aqueous solution); include phase labels. Then, for each, write the net ionic equation. a NaOH + HNO3 b HCl + Ba(OH)2 c HC2H3O2 + Ca(OH)2 d NH3 + HNO3arrow_forward
- Oranges and grapefruits are known as citrus fruits because their acidity comes mainly from citric acid, H3C6H5O7. Calculate the concentration of citric acid in a solution if a 30.00-mL sample is neutralized by 15.10 mL of 0.0100 M KOH. Assume that three acidic hydrogens of each citric acid molecule are neutralized in the reaction.arrow_forwardWhat volume of 0.955 M HCl, in milliliters, is required to titrate 2.152 g of Na2CO3 to the equivalence point? Na2CO3(aq) + 2 HCl(aq) H2O(l) + CO2(g) + NaCl(aq)arrow_forwardComplete and balance each of the following molecular equations (in aqueous solution); include phase labels. Then, for each, write the net ionic equation. a Al(OH)3 + HCl b HClO + Sr(OH)2 c Ba(OH)2 + HC2H3O2 d H2SO4 + KOHarrow_forward
