Sodium Hydroxide is a powerful alkali which reacts with the natural oils in your skin and converts them to soap which results in a "soapy feel" on the skin. The NaOH rapidly eats away at your flesh. It is highly corrosive and you must wash your hands thoroughly and quickly.
how much sodium hydroxide in grams must be added to seawater to precipitate 86.9mg of magnesium present?
use titration formula
To remove any remaining sodium sulfate or sodium hydroxide.
Sodium reacts with moisture, it will eventually turn to sodium hydroxide from moisture in the air. It reacts violently with water.
This is Sodium Hydroxide (NaOH) dissolved in ethanol (CH3CH2OH), this must be done in advance because it takes a bit of time for the NaOH to dissolve in the ethanol as long as you have the equivalents correct.
Sodium hydroxide must be dissociated in water.
No, sodium hydroxide is a strong base so its pH must be higher than 7.

Sodium reacts with moisture, it will eventually turn to sodium hydroxide from moisture in the air. It reacts violently with water.
In a tightly sealed container, preferably one that doesn't have a lot of moisture in the air. The container should be a plastic container as glass container can react with sodium hydroxide and melt.
First, you must either find or be provided with a known mass of sodium hydroxide and a volumetric vessel. You must also know the molecular mass of sodium hydroxide, which is about 40.00. If the volume of sodium is sufficient, you can complete the preparation by determining the volume of the volume of the vessel in litres, multiply this volume by twice the molecular mass of sodium hydroxide, and dissolve the resulting mass in the known volume.
well the theorem is that you must use problematic words such as these to get the right answer. Also it may or may not be because sodium hydroxide react faster than ammonia to produce lather
Sodium hydroxide is alkaline and so its pH must be above 7. It is not a strong base so its pH may be 9 approximately.
Because it dissolves prcipitate that form after addion of sodium hydroxide.
Sulfuric acid must be titrated with a standardized solution of sodium hydroxide.
