Sodium + water reaction, noxious fumes? - Chemistry Stack …
2019年9月24日 · I agree. This is a dangerous reaction and should not be tried without proper equipment, including a lab hood and fire extinguishing equipment. The fumes could be "just" droplets of sodium hydroxide solution. I've seen similar fumes involving hydrochloric acid, just by adding water to rinse out traces of concentrated acid (in a hood, of course).
Why does sodium react with water? - Chemistry Stack Exchange
2013年7月28日 · Sodium is more "electropositive" than hydrogen as it is down on the periodic table. This makes it more reactive to say elements like fluorine or oxygen. In this same way it is reactive to ions like hydroxide. Since water can turn into hydroxide and hydrogen ion the sodium ion is able to displace the hydrogen ion.
How do I calculate the maximum temperature of an exothermic …
2022年2月17日 · $\begingroup$ I suggest using some inert object (e.g. from stainless steel or glass) and measure its heat capacity in a water bath with different initial water and object temperatures. Then measure the heat capacity and calculate the specific heat capacity of the target 14 M NaOH by doing the same with this solution.
Why is the product of sodium and water, sodium hydroxide and …
2017年1月26日 · Additionally sodium oxide can react with hydrogen to form sodium hydroxide and sodium hydride under certain conditions. The reaction is reversible: $$\ce{Na2O + H2 <=> NaOH + NaH}$$ From the first two reaction equations above we can conclude that we also could obtain sodium oxide by reaction of sodium with water.
aqueous solution - What is the net ionic equation of sodium …
2015年4月16日 · $\begingroup$ Your second answer is close but think about the state of sodium hydroxide before dissolving in water. $\endgroup$ – Coconut Commented Apr 16, 2015 at 2:19
Reason for Exothermic reaction? - Chemistry Stack Exchange
2020年1月30日 · Let's start with your statement that "dissolving sodium hydroxide in water is an exothermic process." I assume it is based on the reported standard enthalpy of solvation, which is $-44.2$ kJ/mol. If you go into the lab and try to make a 1 M solution of sodium hydroxide, however, you'll find that the solution gets quite cold.
Reaction between NaOH and CO2 - Chemistry Stack Exchange
2016年8月12日 · If sodium hydroxide solution was highly concentrated like you said, then both equations are wrong since sodium hydroxide solution will strip away the second hydronium as well forming carbonates. All state notations with (aq) implies that it is dissolved in water. If it was pure NaOH, it would be in a solid state under room temperatures.
organic chemistry - Reaction of NaOH with methanol and ethanol ...
2016年9月17日 · The proposed reaction: $$\ce{CH3OH(l) + NaOH(s) <<=> CH3O^-Na+(s) + H2O(l)}$$ According to wikipedia: The solid hydrolyzes in water to give methanol and sodium hydroxide. The equilibrium is biased to the left, as @vapid has mentioned in the comments. To quote him: In the large excess of alcohol, the reaction will be considerably shifted towards ...
What reactions occur when mixing copper sulfate and sodium …
2017年1月26日 · I tried reacting copper sulfate with sodium hydroxide to get copper hydroxide, which should precipitate, according to the following equation: $$\ce{2NaOH + CuSO4 -> Cu(OH)2(s) + Na2SO4}$$ I looked on Google Images, and the color of copper hydroxide is light-blue, but something interesting happened when I mixed these two solutions: the ...
inorganic chemistry - What is the reaction between NaOH and …
2016年5月27日 · In this video it is mentioned that urea and sodium hydroxide will react to produce ammonia. However, I can't seem to find a clear explanation of the reaction and the other products generated. One explanation I found says that the NaOH causes the urea to hydrolyze, yielding sodium carbamate, which will then further hydrolyze to sodium carbonate.
