1. The salt is KNO₃This is a strong acid - strong base reaction. HNO₃ is the strong acid and KOH is the strong of the base. H⁺ in HNO₃ and OH⁻ KOH partner and make H₂O(l). NO₃⁻, and K⁺ couple to make KNO₃ salt. When writing the chemical formulae of positive ion comes first and second is negative ions. The charges should be changed. From positive ion is +1 and negative ion has -1 after the switching of the charges, the product must be KNO₃.Balance the equation is HNO₃(aq) + KOH(aq) → H₂O(l) + KNO₃(aq)2. Salt is Ca(NO₃)₂This is a strong acid - strong the basis of the reaction. HNO₃ is the strong acid and Ca(OH)₂ is the strong base. H⁺ in HNO₃ and OH⁻ from Ca(OH)₂ partner and make H₂O(l). Ca2⁺ and NO₃⁻ par to make the Ca(NO₃)₂ salt. Positive ion is Ca2⁺ that has +2 charge and of negative ions is NO₃⁻ has -1 charge. Switching of the positions of Ca2⁺ gets 1 while NO₃⁻ 2. Therefore, the salt should be of Ca(NO₃)₂.The balanced equation is 2HNO₃(aq) + Ca(OH)₂(aq) → 2H₂O(l) + Ca(NO₃)₂(aq)3. The salt is CaCl₂ This is a strong acid - strong base reaction. HCl is the strong acid and Ca(OH)₂ is the strong base. H⁺ in HCl and OH⁻ from Ca(OH)₂ partner and make H₂O(l). Ca2⁺ and Cl⁻ pair to make CaCl₂ salt. Positive ion is Ca2⁺ that has +2 load and negative ions it is Cl⁻ that has -1 charge. By the change of the charges of Ca2⁺ gets 1 while NO₃⁻ 2. Therefore, the salt should be CaCl₂.Balance the equation is 2HCl(aq) + Ca(OH)₂(aq) → 2H₂O(l) + CaCl₂(aq)4. The salt is KClThis is a strong acid - strong base reaction. HCl is the strong acid and KOH is the strong base. H⁺ in HCl and OH⁻ KOH partner and make H₂O(l). K⁺ and Cl⁻ pair to make KCl salt. Positive Ion is K⁺, which is +1 load and negative ions it is Cl⁻ that has -1 charge. By the change of the charges K⁺ gets 1, and Cl⁻ also gets 1. Therefore, the salt should be of KCl.Balance the equation is HCl(aq) + KOH(aq) → H₂O(l) + KCl(aq)
