What is the OH- in a solution that contains 0.240 g NaOH in 0.225 L of solution?
Molarity = moles solute/Liters solution get moles NaOH 0.240 grams NaOH (1 mole NaOH/39.998 grams) = 0.0060 moles NaOH ----------------------------------as one to one OH- has this many moles also Molarity = 0.0060 moles OH-/0.225 Liters = 0.0267 M OH- ----------------------- -log(0.0267 M OH-) = 14 - 1.573 = 12.4 pH -------------
Is NaOH a strong acid?
NaOH, sodium hydroxide is a strong base. This is because it dissociates completely in solution becoming a strong electrolyte. Na(+) and OH(-) ions in solution.
Do a base release hydroxide ions in solution?
Of course An example: NaOH---------Na+ + OH-
Why is NaOH a strong base?
Because it disassociates almost completely in solution. Na + and OH - ions are almost seen 100% in solution.
How would OH- in an ammonia solution compare with OH- in a sodium hydroxide solution of similar concentration?
They both have the same concentration, but NaOH (Sodium Hydroxide) is more basic than NH4OH (Ammonium Hydroxide), because it breaks apart in H2O more easily. The OH-'s on both of them are technically the same, but the one in NaOH will break off more easily in water than that in NH4OH. Thus, NaOH is a stronger base and a stronger electrolyte.

A solution of NaOH has OH- 1.9 x 10-6 What is the pOH of this solution?
5.7
Which compound produces -OH in a solution?
Bases, for example sodium hydroxide - NaOH.
What is redissolved in excess?
Aluminium hydroxide = Al(OH)3 , and Zinc hydroxide = Zn(OH)2 , is redissolved in excess Sodium hydroxide = NaOH (in water solution) : Al(OH)3 + NaOH + H2O ----> NaAl(OH)4 Zn(OH)2 + NaOH + H2O ----> Na2Zn(OH)4
Why is NaOH a strong acid?
NaOH, sodium hydroxide is a strong base. This is because it dissociates completely in solution becoming a strong electrolyte. Na(+) and OH(-) ions in solution.

What is the complete ionic equation of the reaction FeCl3 solution with NaOh solution?
Fe3+ + 3OH- _____> Fe(OH)3
What compound that produces OH in solution?
Bases, for example NaOH, KOH, LiOH, etc.
Do a base release hydroxide ions in solution?
Of course An example: NaOH---------Na+ + OH-
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.
Why is NaOH a strong base?
Because it disassociates almost completely in solution. Na + and OH - ions are almost seen 100% in solution.
What is the molarity of Na OH solution?
One mole of NaOH is 40g. So 40g dissolved in 1 litre will give a 1M solution.
