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 completely precipitate 86.9mg of magnesium?
how much sodium hydroxide in grams must be added to seawater to precipitate 86.9mg of magnesium present?
What volume mL of a concentrated solution of sodium hydroxide 6.00 M must be diluted to 200.0 mL to make a 0.880 M solution of sodium hydroxide?
use titration formula
Why must cuo precipitate in the funnel be thoroughly washed with water?
To remove any remaining sodium sulfate or sodium hydroxide.
Why must sodium be stored under paraffin?
Sodium reacts with moisture, it will eventually turn to sodium hydroxide from moisture in the air. It reacts violently with water.
What is ethanolic sodium hydroxide?
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.
Why do the solid sodium hydroxide and aluminium powder not react when stored in a sealed container?
Sodium hydroxide must be dissociated in water.
Can sodium hydroxide produce pH of 4?
No, sodium hydroxide is a strong base so its pH must be higher than 7.

Can sodium hydroxide be stored in a Erlenmeyer flask?
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.
How its made 2 M solution of Na OH?
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.
Why do soap manufacturers use sodium hydroxide not ammonia?
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
What is the pH of sodium hidroxide?
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.
Why buffer solution must be used for titration with EDTA?
Because it dissolves prcipitate that form after addion of sodium hydroxide.
How do you 0.02 m sulphuric acid standardization calculation?
Sulfuric acid must be titrated with a standardized solution of sodium hydroxide.
