Question
Write the predicted net ionic equation for that reactions that occurs.(Reacting ionic species should be written as ions and reading molecular species should be written as molecules.)You don't have to balance the equation. Also, for each reaction, classify the reaction as oxidation-reduction, acid-base, decomposition, precipitation, or complex ion. (using some hydrochloric acid) Place about 0.25 g of solid sodium bicarbonate in a 13 times 100 mm test tube. Carefully add about I mL of 3.0 M hydrochloric acid. Observe. In a 13 times 100 mm test tube, mix about 1 mL of 0.10 M sodium bicarbonate and 1 mL of 3.0 M hydrochloric acid. Observe. In a 13 times 100 mm test tube, mix about I mL of 0JLCLM lead nitrate and 1 mL of 3.0 M hydrochloric acid. Observe. In a 13 times 100 mm test tube, mix about I mL of 1.0 M sodium hydroxide and I mL of 1.0 M hydrochloric acid. Observe. In a 20 times 150 mm test rube, mix about 1 mL of 1.0 M aqueous ammonia and 1 mL of 1.0 M hydrochloric acid. Observe.Explanation / Answer
1) HCl(aq) + NaHCO3(aq) NaCl(aq) + H2O(g) + CO2(g) This is neutralisationreaction here H2O is in gases phasse , 2) The given reaction is HCl(aq) +NaHCO3(aq) NaCl(aq) + H2O(l) +CO2(g)Here HCl(aq) is anacidic solution. When mixed with NaHCO3(aq), a basic solution, aneutral salt solution [NaCl(aq)+ H2O(l)] iscreated, releasing energy in the form of heat, and a gas is evolved[CO2(g)]. This is comes underAcid -Base reaction . 3) Pb(NO3)2(aq)+ 2HCl(aq) --> PbCl2(s) + 2HNO3(aq)
This produces aninsoluble product, lead (II) chloride. HNO3 is nitricacid and is completely soluble in water. This is comes underPrecipitate reaction. 4) H+(aq) +Cl–(aq) + Na+(aq) +OH–(aq) --> Na+(aq) +Cl–(aq) + H2O (aq) This is comes underAcid base neutralisation reaction . 5) NH3 (aq)+HCl (aq)--------> NH4Cl (s) this is comes underPrecipitation reaction .
