This is a neutralization reaction. This reaction should result in producing a salt and water. Sodium chromate is the salt in this instance.
Ammonia and sodium chloride are formed.
Sodium sulphate + water formed
Sodium reacts with water to produce Sodium hydroxide and Hydrogen gas.2Na + 2H2O = 2NaOH + H2
A white hydroxide: Ca(OH)2.
That sounds right.
The insoluble in water copper(II) hydroxide is formed.
Sodium sulphate + water formed
Ammonia and sodium chloride are formed.
Sodium reacts with water to produce Sodium hydroxide and Hydrogen gas.2Na + 2H2O = 2NaOH + H2
That sounds right.
A white hydroxide: Ca(OH)2.
That sounds right.
Hydrogen gas is given out when sodium hydroxide reacts with a metal.
sodium in water reacts by this mechanism; Na + H2O = NaOH + H when ballanced this is; 2Na + 2H2O = 2NaOH + H2 the end products are sodium hydroxide and hydrogen gas (which normally burns due to the heat of the reaction) and of course there remains unreacted water. please be carefull when doing this though because the reaction is violent and the sodium hydroxide formed is very caustic (dangerous to get on your skin or eyes)
No Sodium hydroxide solution results -- not sodium chloride.
There is no reaction. "Hydroxide acid" is water, which does not react with sodium hydroxide.
