1) #NaOH# is in solid state: No reaction. Some researchers used HNO3 to remove this layer. Sign in. 2.5. The bandage was fabricated as a double-layer structure. Join Yahoo Answers and get 100 points … Lv 4. $$\ce{3NaNO3 + 8Al + 5NaOH + 18H2O -> 8Na[Al(OH)4] + 3NH3(g)}$$ How does ammonia evolve here? 0 0. Al And Naoh. It is definitely +3 Also, the reaction of Al + NaOH will be VERY exothermic. aluminium has a lower tendency to lose or give electrons than sodium. 1 decade ago. Sodium hydroxide, also known as lye and caustic soda, is an inorganic compound with the formula NaOH. Al(s) + 3Na(OH)(aq)---> Al(OH)3(aq) + 3Na(s) 2 Al + 2 NaOH + 2 H2O → 2 NaAlO2 + 3 H2. Direct link to this balanced equation: Instructions on balancing chemical equations: Enter an equation of a chemical reaction and click 'Balance'. 2 Al + 6 H2O -----> 2 Al(OH)3 + 3 H2. 2) Reaction is at room temperature, and the #NaOH# is aqueous: No reaction, as aluminium is a weaker reducing agent than sodium, i.e. How do you think about the answers? Source(s): chemical reactions al naoh: https://shortly.im/JT0ma. Based on the thermal and expansion behavior of Al-NaOH-composited eGaIn, a smart water-triggered bandage was designed. Ask question + 100. It is a white solid ionic compound consisting of sodium cations Na + and hydroxide anions OH −. ammonia acts as a catalyst. It is definitely +3. It is not soluble in excess of NaOH. Is it that we get hydrogen gas evolving in the reaction between Al and NaOH, and this gas reacts with the NO3 anion? Source(s): https://owly.im/a9048. Still have questions? Avantika. 0 0. redbeardthegiant. I there a logical way to deduce this, or should one just memorize that "Al and Zn reduce $\ce{NO3-}$ to ammonia in basic solutions"? 2 1. Al (s) + NaOH -----> Al2O3 +NaOH -----> thank you! 9 years ago. Lv 7. of calcium hydroxide with sodium hydroxide IF the concentration of calcium ion is high. P.S. skipper . You can sign in to vote the answer. Its internal side was composed of Al-NaOH-composited eGaIn and the … 1 decade ago. The Al-NaOH-composited eGaIn and reaction products were analyzed separately. 0 4. Normally, a smut layer will be formed resulting from the reaction of NaOH and Al. If aluminum is coated with an atomic layer of Hg to remove the surface oxide, you get the same result, Al reacts with water to liberate hydrogen and form Al(OH)3. Lv 5. 4 years ago. Al: 2: 26.9815386: NaOH: 2: 39.99710928: H 2 O: 6: 18.01528: NaAl(OH) 4: 2: 118.00066788: H 2: 3: 2.01588: Units: molar mass - g/mol, weight - g. Please tell about this free chemistry software to your friends! 0 0. Design of the liquid metal-based smart bandage. or more simply Al(OH) 3 (s) + OH – (aq) ==> [Al(OH) 4] – (aq) (amphoteric behaviour because it dissolves in acids too) calcium ion: Ca 2+ (aq) + 2OH – (aq) ==> Ca(OH) 2(s) gives a white precipitate.
