What is the molarity of 5.60 mol of sodium carbonate in 1500 ml of solution?
Molarity = moles of solute/Liters of solution ( 1500 mL = 1.5 Liters ) Molarity = 0.800 moles NaOH/1.5 Liters = 0.533 M sodium hydroxide ...
How do you distinguish sodium hydroxide and sodium acetate?
To test presence of Sodium ions, do a flame test: color observed: golden yellow. To test presence of carbonate or hydrogen carbonate ions: Take some of the sodium hydrogen carbonate in a dry test tube. Heat the test tube and bubble the gas through limewater. Limewater turns milky. Carbonate or hydrogen carbonate ions present. To distinguish between carbonate and hydrogen carbonate: Add indicator solution. If colour of solution turns green, pH is 7-8, hydrogen carbonate ions are present. If colour of solution turns blue, pH is 12-13, carbonate ions are present. -Iberuz
What is the molarity of a solution in which 0.800 moles of sodium hydroxide is dissolved in 1500 ml of solution?
n=CV/1000 Where n = number of moles, C= Molarity concentration of the solution, and V= volume of the solution in milliliter's We are given, n=0.150, V=8.16 liters(8160 milliliters)and C is not given. Solving for C from the equation above we get: C=(n*1000)/V C= (0.150*1000)/8160 C= 0.018 The molarity of the solution is 0.018
What do you get when you mix iron3 nitrate with sodium hydroxide?
precipitated Fe(OH)3 = ferric hydroxide or Fe(OH)4-(aq) = ferrate anion in solution, when in excess of hydroxide
What is the molarity of Na plus ions in a 0.25 M solution of Na3PO4?
So you have 0.25 molar Na3PO4. But for every one molecule of Sodium phosphate, you have 3 molecules of sodium. Therefore you have 0.25*3 or 0.75 molar sodium.

What is the Method of preparation of 3 percent solution of sodium hydroxide?
30 gm of sodium hydroxide desolved in 1 litre distilled water.
What happens if you mix ferric sulphate and sodium hydroxide?
Solid ferric hydroxide, Fe(OH)3, precipitates out of solution. The resulting sodium sulphate remains dissolved.

How could you separate magnesium hydroxide Mg(OH)2 from alminium hydroxide Al(OH)3?
Add sodium hydroxide solution; aluminium hydroxide will dissolve but Mg(OH)2 remain.

What volume of 0.200 molarity phosphoric acid will react completely with 50ml of 0.100 molarity sodium hydroxide?
Phosphoric Acid dissociates to give off 3H+ ions, meaning that one mole of Phosphoric acid reacts with three mols of sodium hydroxide. Using the equation n = c x v n = 0.1 x 0.05 =0.005 mols of OH ions in the solution therefore there are 0.005/3 = 0.00167 So the volume of phosphoric acid - v = n/c v = 0.00167/0.2 v = 0.00835 l = 8.4ml of Phosphoric Acid reacts completely with Sodium hydroxide
What is the 3 letter symbol for sodium hydroxide?
The chemical formula (not symbol) of sodium hydroxide is NaOH.
3M sodium hydroxide?
C2H4O2 + NaOH = H2O + C2H3O2Na Acetic acid (60 gm) + sodium hydroxide ( 40 gm) = 100 gm water (18 gm) + sodium acetate (82 gm) = 100 gm Ratio reactants to products = 1:1 Molarity = moles / L, 3M = 3 moles / 1 L Acetic acid = 60 gm / total reactant 100gm = 1.8 moles Multiply by 3 = 1.8 moles or 180 grams Sodium Hydroxide = 40 gm / total reactant 100 mg = 1.2 moles or 120 grams. 180 grams acetic acid + 120 grams sodium hydroxide = 300 grams. 300 grams divided by 1 liter = 3M So in order to make 3 M sodium acetate combine solution, add 180 grams acetic acid and 120 grams sodium hydroxide with 1 liter of water.
