the net ionic equation is : Mg2+(aq)+2OH-(aq)-->Mg(OH)2(s) r u in mastering chem? :P
MgCl2 (aq) + 2NaOH (aq) --> Mg(OH)2 (s) + 2NaCl (aq)
Mg(NH4)PO4 (s) + HCl (aq) --> Mg(2+)(aq) + NH4Cl (aq) + HPO4(2-)
Magnesium hydroxide, Mg(OH)2 precipitates.
2NaOH(aq) + MgCl2(aq) --> 2NaCl(aq) + Mg(OH)2(s)
The chemical reaction is:
MgCl2 + Ca(OH)2 = Mg(OH)2 + CaCl2
Mg^(2+) + OH- => Mg(OH)2
Zn2+(aq)+2OH−(aq)→Zn(OH)2(s)
This solution contain 26,3 g NaOH.
4.00 grams of NaOH have been added to 2.00 liters of water. The molarity of this solution is?
You have to realise that a drop from the burette for instance is insignificant, if you are dealing with at least 10ml solution which you usually deal with on a titration. If you don't want to regard it as insignificant, then if NaOH is in the burette, then the solution doesn't become more concentrated with NaOH because that drop escaped.
The answer is 0,625 moles.
Methyl orange shows yellow color in an NaOH solution.

Phenolphthlalein is something like a pH indicator. When it is added to a liquid and the liquid turns pink, it means that the latter substance is basic.When the solution is added with NaOH, it will turn pink.Note that NaOH serves as a carbon dioxide neutralizer.The color of the solution will slowly fade after some time, because carbon dioxide is present in the air neutralizing the color effect of the NaOH.
Nothing; other than; adding Solid NaOH or diluting a solution of NaOH with NaCl solution, will produce energy, resulting in a temperature increase.
NaOH is added to p-nitrophenol to change it into p-nitropenyl, which can give the maximum Absorption.

560 g in 350 ml (But I am not sure if that large quantity of NaOH will dissolve in 350 ml of wate).
The answer is 0,625 moles.
It is possible only if you evaporate the water.
