What is the name of the polyatomic ion NaOH?
NaOH is Sodium Hydroxide.
How many moles are in gram of NaOH?
moles = mass/Mr moles = 100/(23+16+1) moles of NaOH = 2.5mol
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.
What is he formula for sodium hydroxide?
The chemical formula for sodium hydroxide is NaOH.
What is the difference between NaOH s and NaOH aq?
NaOH (s) refers to solid sodium hydroxide, which is in a solid state. NaOH (aq) refers to sodium hydroxide dissolved in water, resulting in an aqueous solution. The (s) and (aq) notations distinguish between the physical states of the substance.
Why the NaOH solution is heated before adding BaCl2 in the two solutions method for determination of purity of NaOH sample?
Why the NaOH is heated before adding in BaCl2 for determination of purity of NaOH sample?
Why is NaOH heated before adding BaCl2?
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.
What happens to sodium hydroxide when heated?
At very high temperature NaOH is decomposed and Na2O fumes are emited.The reaction is:2 NaOH = Na2O = H2O
Why is it necessary to standardize the NaOH solution before titration?
Standardizing the NaOH solution before titration is important to accurately determine its actual concentration. This ensures the accuracy and reliability of the titration results by eliminating any discrepancies that may arise from variations in the concentration of the NaOH solution.
Can we use strong solution of NaOH to make sodium extract instead of sodium metal?
No, using a strong solution of NaOH to make sodium extract is not practical due to the high reactivity of sodium with water. Sodium metal is typically produced through electrolysis of molten sodium chloride (NaCl) or other methods that involve isolation of the pure metal.
What happens when NaOH plus NaAlO2 is heated in presence of N2?
Heating NaOH and NaAlO2 in the presence of N2 can lead to the formation of sodium alanate (Na3AlH6), which is a complex hydride used in hydrogen storage applications. This reaction involves the reduction of sodium aluminate by sodium hydroxide in the presence of nitrogen gas.
Which compound is produced when ethanal is heated with dilute NaOH solutions?
When ethanal (acetaldehyde) is heated with dilute NaOH solutions, it undergoes an aldol condensation reaction, ultimately leading to the formation of β-hydroxybutyraldehyde. This compound can further dehydrate to yield crotonaldehyde (2-butenal) as the final product. The reaction is a classic example of the aldol reaction, where two molecules of ethanal react under basic conditions.
What is the mass of 3.42 moles of NaOH?
3.42 moles NaOH (39.998 grams/1 mole NaOH) = 137 grams NaOH
How many grams of NaOH are there in 5.2 moles NaOH?
208g NaOH
How do you calculate of NaOH in solution procedure?
To calculate the concentration of NaOH in a solution, you would typically measure the volume of the solution and the amount of NaOH used to prepare it. Then, you can use the formula: Concentration (in mol/L) = amount of NaOH (in mol) / volume of solution (in L) to determine the concentration. Make sure to convert any given amount of NaOH from grams to moles before calculating.
0.01N NAOH solution preparation?
To prepare a 0.01N NaOH solution, you would need to dissolve 0.4 grams of NaOH in 1 liter of water. Make sure to wear proper protective gear and use a glass stirring rod to dissolve the NaOH slowly in the water to prevent splattering. Measure and mix thoroughly to ensure uniformity of the solution before use.
Which compound should be heated with soda lime to obtain ethane gas in the laboratory its equation?
Sodium propanoate (or propionate) when heated with soda lime ethane gas is produced.
