The chemical equation of the reaction between $NaHSO3 $and $NaOx $is: $NaHSO3 + NaOx = Na2SO3 + H2O $. Rewriting it into an ion equation,$NaHSO3 $is an acid salt of a weak acid, which can be dissociated into $Na^+$and $HSO3 ^-$in solution.$NaH $is a strong base, which can be completely dissociated into $Na^+$and $Oh^-$in solution. After the reaction,$Na2SO3 $is a strong solute, which can be completely dissociated into $Na^+$and $SO3 ^{2 - }$. The ion equation is: $HSO3 ^-+ SH ^- = SO3 ^{2 - }+ H2O $. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Under acidic conditions, manganate (Mn O42-) will react with hydrogen dioxide (H2O2). The ion equation is: Mn O42- +2H2O2 + 4H + = Mn2+ +4H2O +2O2. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The chemical equation of the reaction between Na2SO4 and ClCl2 is Na2SO4 + Cl2 = NaHSO4 + Cl2. Because the HSO4 ^-in water was partially ionised, after adding a strong acid such as sulfuric acid, the reaction formed a weaker acidic HSO4 ^-ion. The ion equation for this reaction is: <i>(SO4 ^{2 - }+H^+ = HSO4 ^-<i>). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Aluminiothermic reaction 2AI + Fe2 O2 = 2Fe + Al2 O2. Since the reagents, iron dioxide and aluminum, were both difficult to dissolve, the reaction was carried out in a solid state. There was no ion in the water solution or molten state, so there was no ion equation for this reaction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

There was no reaction between aluminum ions (Al3 +) and Na2SO4. In common chemical reactions, aluminum ions and sulfuric acid ions could coexist in solution, and there would be no oxidoreduction reaction, metathesis reaction, etc., so there was no reaction equation. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The ion equation of the reaction between the reagent and the acid would vary depending on the type of acid. Using sulfuric acid as an example: Borax will react with water: $Na2B4O7 + 7H2O = 2Na^+++4H3BO3 + 20H ^ -$. When it reacted with sulfuric acid,$Oh^ -$would react with $H^+$, and the total ion equation was: $B4O7 ^{2 -}+2H ^+++5H2O = 4H3BO3 $. Borax reacted with acid to form Boric acid ($H3BO3 $). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The ion equation is: $2Fe^{2 + } + H_{2}O_{2} + 2H^{+}=2Fe^{3 + } +2HO $. Reaction phenomenon: The solution turns from light green to yellow (because the iron ions are light green, the iron ions generated after the reaction are yellow). There may be a deposit during the reaction (when there are other ions in the solution that can form a deposit with the iron ions). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

For the reaction between sulfur and metal, the following are the common reactions and situations: - Sulfur and iron reaction: The chemical equation is: FeS + S = (heating)FeS. This reaction does not involve free moving ions, so it cannot be rewritten as an ion equation. The phenomenon was the formation of black solid iron Sulphide. - Sulfur and copper reaction: The chemical equation is 2Cu + S = (heating) Cu2 S. Similarly, the ion equation cannot be written. The phenomenon was the formation of black cuprous sulfur solid. - Sulfur and Na reaction: The chemical equation is 2Na + S =(grinding)Na <2> S. There is no need to rewrite the ion equation. The phenomenon was that during the grinding process, a violent reaction formed a white solid of sulfur dioxide. - Sulfur and aluminum reaction: The chemical equation is 3S +2AI = Al2S, which cannot be rewritten as an ion equation. The reaction phenomenon was the formation of aluminum sulfur solid. - Sulfur and mercury reaction: The chemical equation is as follows: Mercury + S = HgS, which cannot be written as an ion equation. The reaction phenomenon is the formation of black mercury sulfur solid. In general, since most of these reactions were solid-state reactions or did not carry out the ionisation process in the solution system, there was basically no ion equation. Most of the reaction phenomena were the formation of the corresponding sulfur solid, and the color of the solid was different. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The reaction between Cl2 and Ox had different ion equations depending on the reaction conditions. - When Cl2 reacted with a cold, diluted solution of soda, the ion equation of the reaction was: [Cl2 + 20H ^- = Cl2 ^-+ ClO^-+ H2O]. - When Cl2 reacted with hot, concentrated solution of NaOx, the ion equation of the reaction was: [3Cl2 + 60H ^- = 5Cl2 ^-+ ClO3 ^-+3H2O]. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
