What is the molarity of 30% NaOH?
In the question, we have been given that $NaOH$ is present in 30 percent weight by volume. So, if we take a solution, weighing 100 grams, the amount of $NaOH$ that will be present in it should correspond to 30 grams. On solving, we get the final molarity as 7.5 M.
How do you make a 15% NaOH solution?
From given, 15 grams of sodium hydroxide is present in 100 grams of solution. So, to make 50 g of 15%(w/w) sodium hydroxide solution, 47.2 mL of water is needed under experimental conditions.
What is the molarity of 25 NaOH?
Answer. Answer: Molarity( M)= weight of solute in gm/ litre ÷ Gram Molecular Weight. 25% NaOH 40gm of NaIH in 100 ml Solution.
What is the molarity of 40% NaOH?
13. Molarity of 40% NaOH (w/w) solution is 12M.
How do you make a 25 NaOH solution?
25% NaOH 40gm of NaIH in 100 ml Solution.
What is the viscosity of NaOH at different temperatures?
For example, 50% NaOH has a viscosity of ~ 87 cP at 77°F (25°C), but this drops to only 3 cP at 212°F (100°C). At caustic concentrations below 10%, the viscosity vs. temperature characteristic is close to that of water (see table on next page).
What is sodium hydroxide (NaOH)?
Sodium hydroxide (NaOH), or lye, is used in papermills, water treatment plants, and any number of a variety of other places. It is very often used for pH control (to raise it) as it is very alkaline, or basic.
What is the OSHA exposure limit for sodium hydroxide?
SODIUM HYDROXIDE SOLUTIONS (MORE THAN 10% NaOH) Airborne Exposure Limits: – OSHA Permissible Exposure Limit (PEL): 2 mg/m3 Ceiling – ACGIH Threshold Limit Value (TLV): 2 mg/m3 Ceiling Ventilation System: A system of local and/or general exhaust is recommended to keep employee exposures below the Airborne Exposure Limits.
What are the treatment options for sodium hydroxide corrosion?
SODIUM HYDROXIDE SOLUTIONS (MORE THAN 10% NaOH) corrosion, the use of therapeutic doses of steroids should be considered. General supportive measures with continual monitoring of gas exchange, acid-base balance, electrolytes, and fluid intake are also required.
