The concentration of sodium hydroxide in solution is determined by titration with an acid solution.
0.0280 moles
It is possible only if you evaporate the water.
The concentration of this solution (in NaOH) is 40 g/L.
standardization of NaoH
40 grams, this is the 1M NaOH standard laboratory solution.
0.0280 moles
This solution contain 26,3 g NaOH.
It is possible only if you evaporate the water.
The answer is 0,625 moles.
The concentration of this solution (in NaOH) is 40 g/L.
standardization of NaoH
40 grams, this is the 1M NaOH standard laboratory solution.
Methyl orange shows yellow color in an NaOH solution.
50 g x 1 mol/40 g = 1.25 moles1.25 moles NaOH/0.2 kg = 6.25 molal
100 g of solution containing 50 g of NaOH.
Can use this way. -log(0.001) = 3 14 - 3 = a pH of 11.0
One liter of a one molar solution of NaOH in water contains 40g of NaOH. The quantity must be known.
