What is the viscosity of sodium hydroxide?
What is the viscosity of sodium hydroxide?
around 78cp
Sodium hydroxide has a characteristic viscosity that adds to its storage difficulties and chemical hazards. At 68°F (20°C), a 50% NaOH solution will have a viscosity rating around 78cp (centipoise; 1cp = 1mPas). For reference, water is around 1.0cp at this temperature and olive oil around 85cp.
What is the molarity of 25% sodium hydroxide?
Molarity( M)= weight of solute in gm/ litre ÷ Gram Molecular Weight. 25% NaOH 40gm of NaIH in 100 ml Solution.

What is sodium hydroxide 50%?
Sodium Hydroxide 50% solution (NaOH) is colorless and odorless that can react violently with strong acids and water. It is used in chemical manufacturing, oil refining, hydraulic fracturing, water treatment, and metal processing. Applications: Commonly used as a Drain Cleaner.
What is the viscosity of sodium?
0.072 centipoise
The critical absolute viscosity of sodium is 0.072 centipoise and that of potassium 0.055 centipoise, the estimated precision being plus or minus 0.01 centipoise. The critical absolute viscosities of metals are higher than those of covalent or homopolar substances of van der Waals type.
How do you convert centistokes to Centipoises?
Centipoise = centistokes x specific gravity where specific gravity is assumed to be 0.8 (except for water). To find the exact cp of your fluid: cp = cSt x (weight per gallon x 0.120).
What is the molarity of 25% and solution?
25%(wv) solution of HCl corresponds to 25g of HCl present in 100 mL of solution. Molarity=25036.5×10001000=6.85 M(GMW of HCl) = 36.5) .
What is the normality of 25 sodium hydroxide?
0.1N
Normality and molarity of sodium hydroxide are the same. The normality of 10% is 2.5 so, in theory at least, diluting it 25 times should render a normality of 0.1N.
What is specific gravity of water?
1
4.6. The specific gravity of a liquid is the relative weight of that liquid compared to an equal volume of water. The specific gravity of water is de facto 1. Liquids that are lighter than water have a specific gravity less than 1 and those heavier than water have a specific gravity greater than 1.

What are the physical properties of sodium hydroxide?
NAOH module. The NaOH module calculates the physical properties of aqueous sodium hydroxide solutions in the temperature range from 20 °C to 100 °C and in the concentration range from 0 to 50 Ma-% NaOH. The following physical properties are calculated: Density. Specific heat capacity. Thermal conductivity. Dynamic viscosity. Kinematic viscosity.
What is the viscosity of NaOH in water?
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 can sodium hydroxide ( NaOH ) be used for?
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 kind of cleaner has sodium hydroxide in it?
It is commonly present in commercial drain and oven cleaners. Sodium hydroxide is also known as lye or soda , or caustic soda. At room temperature, sodium hydroxide is a white crystalline odorless solid that absorbs moisture from the air.
