What mass of NaOH is required to make up 100 mL of a 0.5000 M solution?
Two parts.Molarity = moles of solute/Liters of solution ( 100 mL = 0.1 Liters )0.5000 M NaOH = X moles/0.1 L= 0.05 moles NaOH--------------------------------now,0.05 moles NaOH (39.998 grams/1 mole NaOH)= 1.99 grams NaOH required====================( could call it 2.00 grams )
How many grams of NaOH must be added to 0.250 L of water to form a solution of pH equals 10.0?
a pH=10 solution of NaOH should contain 0,0001 moles of NaOH/liter. (1 mole/liter for pH=14, 0,1 for pH=13, etc.) A mole of NaOH is 40g-s. (Na=23g O=16g H=1g) 0,0001 mole is 0,004gs. You need the amount necessary for a quarter of a liter, so you divide by four. The result is that you need 0,001gs of NaOH. So if you need to make that solution without any precise laboratory equipment, you should make much larger quantities and just measure 0,250 l-s.
What is the molar concentration of a solution made by dissolving 4.0g of NaOH in enough water to make 1.0 L of solution?
C1V1 = C2V24 x .04 = 1 x V2V2 = (4 x .04)/1= 160mLTherefore the volume of water that needs to be added is 120mL (minus the original volume).
Why is it necessary to keep the standard solution in a clean and dry reagent bottle?
Standardized Sodium Hydroxide (NaOH), as most laboratory chemicals should be stored in a sealed bottle to avoid evaporation of the Water portion, which in turn would increase the concentration of the NaOH over time. (this can be observed experimentally by placing a drop of the NaOH(aq) solution on a safe surface and allowing it to evaporate. The H2O(l) will evaporate leaving NaOH(s) behind in the form of white crystals.) Additional advice which is important with NaOH in-particular is to store the solution in a bottle that does not use a (ground) glass stopper. This is because NaOH dissolves glass. When in low concentrations this process precedes rather slowly, and may simply make the glass-on-glass stopper joint difficult to open. Stronger solutions are capable of freezing the joint permanently! (for an extreme example Sodium Hydroxide heated above its melting point to the liquid phase readily dissolves solid glass into a solution! This is not an experiment that should be attempted but only used for comprehension of why the phenomena occurs)

How do you make 0.1M solution of NaOH?
a solution of 0.1M NaOH has been prepared.How would you make 1L of the same solution
Can we make 1N NaOH solution from 0.1N NaOH solution?
It is possible only if you evaporate the water.
How to prepare 2N solution of NaOH in 10 ml of water?
we need 0.8gm NaoH and dissolved in 10 ml of water to make 2N solution of NaoH .

What amount of solid naoh must be added to 750 g of an aqueous solution to make 2.5 percent NAOH solution by mass?
75gm
How we can make 2 NaOH solution?
If you think to a 2 M solution dissolve 80 g NaOH in 1 L demineralized water at 20 0C.
What is the ionic formula for sodium hydroxide?
NaOH and H2O form a solution of Na+(aq) and OH-(aq) ions (the solvent water, aq, is written as subscripted (aq) ) To make 1 Normal solution you need to know the equivalent of NaOH, which is calculated by dividing Molecular weight by 1, that is 40 divided by 1= 40. So the equivalent weight of NaOH is 40. To make 1 N solution, dissolve 40.00 g of sodium hydroxide in water to make volume of 1 liter.
5.012g of oxalic acid hydrate is dissolved in enough water to make 100 ml of solution. this solution is stitrated with a standardized NaOH solution. It required 39.40 ml of 2.02 M NaOH to reach the?

What volume of 2.5 M NaOH solution is required to prepare 2.0 liters of a 0.75M NaOH?
Simple equality will do here as you have three things and require a fourth. (X L)(2.5 M NaOH) = (2.0 L)(0.75 M NaOH) 2.5X = 1.5 X = 0.60 Liters needed ================
Is it possible to prepare a standard NaOH solution by dissolving an accurate amount of NaOH pellets in a known volume of water?
you can't make a primay standard solution with NaOh.as NaOh is said to be a secondary standard you have to establish the normality using some primary standard acids.
Can you make naoh at home by electrolysis of nacl solution?
Yes, it is possible to make NaOH this way. However, when NaCl is being electrolysed, Cl2 and H2 gasses are released (and NaOH stays in solution). Cl2 reacts with NaOH, forming NaClO, so chlorine gas should be kept away from solution. Also, it should not be forgotten that hydrogen gas is flammable and if one breathes in chlorine gas, his lungs might (and when higher amounts are breathed in - will) burn and be literally coughed out.
How do you prepare 2 liters of 0.75 N Na OH?
Take 60 gm NaOH (100%) disolve it in distilled water, and make up to 2.0 liter by distlilled water.the prepared solution is 0.75 N NaoH Solution.
