NaOH is a strong base.It helps in the manufacture of NaCl that is the salt we used in day to day life.
Molarity = moles of solute/Liters of solution 3.42 M NaOH = 1.3 moles NaOH/Liters NaOH Liters NaOH = 1.3 moles NaOH/3.42 M NaOH = 0.38 Liters
I assume you mean 32.0 grams of NaOH and 450 milliliters of NaOH. Molarity = moles of solute/Liters of solution ( 450 ml = 0.450 liters ) get moles of NaOH 32.0 grams NaOH (1 mole NaOH/39.998 grams) = 0.800 moles NaOH Molarity = 0.800 moles NaOH/0.450 liters = 1.78 Molar NaOH
This solution contain 26,3 g NaOH.
Why the NaOH is heated before adding in BaCl2 for determination of purity of NaOH sample?
8 g NaOH x 1 mole NaOH/40 g = 0.2 moles NaOH
it is a base
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.
3.42 moles NaOH (39.998 grams/1 mole NaOH) = 137 grams NaOH
208g NaOH
Molarity = moles of solute/Liters of solution 3.42 M NaOH = 1.3 moles NaOH/Liters NaOH Liters NaOH = 1.3 moles NaOH/3.42 M NaOH = 0.38 Liters
NaOH is a base.
NaOH is a base.
NaOH is Sodium Hydroxide.
NaOH.
ashes have some NaOH in them
NaOH is a base.
Heating NaOH before adding BaCl2 helps to dissolve NaOH completely in water, ensuring that no solid NaOH remains undissolved in the solution. This is important because the reaction between BaCl2 and NaOH requires the NaOH to be in solution to react with the BaCl2. Heating the solution can also speed up the reaction between NaOH and BaCl2.
