However, the following solution is the preferred answer because ammonium hydroxide is not a compound that exists. Use H3O+ instead This is a base that would ionize completely, and the dissociation equation would look like this: Ca(OH)2 <----> Ca2+ 2OH- , but how would I write the Bronsted equation with water? The full chemical equation is: CaSO4 + 2HCl --> H2SO4 + CaCl2 This states that calcium sulfate plus hydrochloric acid becomes sulfuric acid and calcium chloride. That's a bit of a trap because you're thinking about what it would be, but the net ionic doesn't exist because the "reaction" is actually NR. There is no need to include water in the ionization equation, you just need to include the states in your equation: #Ca(OH)_2(s) -> Ca^(2+)(aq) + OH^(-)(aq) #. C. Strong Acid + Weak Base You know NaCl is soluble. Write the balanced molecular equation.2. Finally, we cross out any spectator ions (ions that appear on both sides of the equation).General Steps:1. All four substances are soluble in solution and all four substances ionize in solution. Net Ionic Equation A. Metal ions are positively charged particles formed when a metal atom loses one or more electrons. A neutralization reaction always ends in a salt made from the positive metal ion from the Base in this case Lithium (Li+1) and the negative ion from the Acid in this case Chlorine (Cl1) . 1) This certainly appears to be a double replacement reaction: I deleted the state symbols from the products. That's because you might think the formula As(OH)3 is a hydroxide and, thus, think that the hydrogen ion reacts with the arsenic hydroxide (which is the wrong name for the compound) to give this wrong answer: and conclude that no reaction took place, that the AsCl3 simply dissolved in water and ionized. Medium Solution Verified by Toppr Ca(OH) 2(s)+2HNO 3(aq)Ca(NO 3) 2(aq)+2H 2O(l) Was this answer helpful? Both reactants are soluble and strong electrolytes (they ionize 100% in solution).
