A solution is prepared by mixing 360.0 mL of 0.25 M NaOH with 140.0 mL of 0.50 M NaOH and the final concentration is?
The concentration is 12,8 g/L NaOH.
When 5.12 g of NaOH were dissolved in 51.55 g water?
The concentration of NaOH is 99,32 g/L.
What is the HCl concentration if 53.1 mL of 0.300 M NaOH is required to titrate a 15.0 mL sample of the acid?
HCl + NaOH ---> NaCl + H2O(53.1 ml)(0.300 M) = (15.0 ml)(x M)x = 1.06 M
What concentration of aqueous NaOH solution freezes at -3.2ºC The freezing point of pure water is 0.0ºC and Kf of pure water is -1.86ºC m?
-10.6c
What is the pH of 7 percent NaOH solution?
How to work it out - Calculate the concentration of the solution in terms of molarity. Calculate the hydrogen ion concentration from the fact that multiplying the hydrogen and hydroxide concentrations (in mols per litre) will always give 1x10-14. Take the -log10 of the hydrogen ion concentration.
When NaH is added to water the hydroxide concentration increases what can you include about NaOH?
The premise of this question is incorrect. When NaOH is added to water the hydroxide concentration increases. NaOH is a base. If a substance decreases hydroxide concentration it would be an acid.
Why is it necessary to standardize the NaOH solution before titration?
It allows the concentration of the NaOH to be known.
A solution is prepared by mixing 360.0 mL of 0.25 M NaOH with 140.0 mL of 0.50 M NaOH and the final concentration is?
The concentration is 12,8 g/L NaOH.
When NaOH is diluted to half of its original concentration what affect does this have on titration?
It should take just exactly twice the volume to reach the balance point.
How is a solution of NaOH prepared dissolving 20g of NaOH in 500ml of distiled water solved?
The concentration of this solution (in NaOH) is 40 g/L.
Does HCl change in concentration when neutralized with NaOH?
fap
What is the pH of Pepsin in NaOH?
it depends on the concentration of NaOH, pepsin, buffer used, ... that cannot be answered in that way...
When 5.12 g of NaOH were dissolved in 51.55 g water?
The concentration of NaOH is 99,32 g/L.
What concentration of aqueous NaOH solution freezes at -3.2ºC?
0.86
Will NaOH increase decrease or no change in pH when added to water?
increase
What is relationship between specific gravity and concentration of sodium hydroxide?
Increasing the concentration of NaOH the density also increase.
How many moles of HNO3 are needed to prepare 5.0 liters of 2.0m soultion of HNO3?
Concentration of NaOH = 0.025 M = 0.025 Moles per Litre of SolutionVolume of Solution required = 5.00LWe can say therefore that:Number of Moles of NaOH needed to prepare the solution= Concentration of NaOH * Volume of Solution requiredTherefore:Number of Moles of NaOH needed to prepare the solution= 0.025M * 5.00L= 0.125molesFrom this we can say that 0.125 moles of NaOH are needed to prepare a 5.00 L solution with a concentration of 0.025M of NaOH.
