How do you prepare 100ml 0.1M of oxalic acid solution?
Firstly you find how much solid oxalic acid you will need, via n = c/v, where: n= number of molesc = concentrationv = volume, in this casen=(.1/.25)=.4 molesNow, from this we can find how many grams of solid oxalic acid we will need, usingn=m/M, wheren= number of molesm = massM = molecular mass, in this casem = nM (through manipulation of the equation)= (.4)(90.03)= 36.012 gNow, you would need to take this pure oxalic acid and add it to a 250mL volumetric flask and fill to you reach the marker.
How toPreperation and standardisation of 0.1n oxalic acid?
To prepare 0.1N oxalic acid solution, dissolve 6.3g of oxalic acid dihydrate (H2C2O4·2H2O) in 1 liter of distilled water. To standardize the solution, titrate it against a standardized solution of sodium hydroxide (NaOH) using phenolphthalein as an indicator until a faint pink color persists for at least 30 seconds. Calculate the concentration of the oxalic acid solution using the equation: (N1)(V1) = (N2)(V2), where N is the normality and V is the volume. Adjust the concentration accordingly for accuracy.
N-phenylanthranilic acid indicator how to prepare?
To prepare N-phenylanthranilic acid indicator, dissolve 0.1 g of N-phenylanthranilic acid in 100 ml of ethanol or methanol. This will create a stock solution of the indicator that can be diluted further as needed for specific applications.
Ho to prepare 0.02 N sulfuric acid?
To prepare 0.02 N sulfuric acid, dilute concentrated sulfuric acid with water in a specific ratio. For example, to prepare 100 ml of 0.02 N sulfuric acid, you would mix 0.4 ml of concentrated sulfuric acid (98% purity) with 99.6 ml of water. It's crucial to handle concentrated sulfuric acid with caution due to its corrosive nature.

How do you prepare standard solution of oxalic acid?
Oxalic acid (M.W.= 90 g/mol) is available in the lab as oxalic acid dihydrate crystals (M.W. = 126 g/mol). A standard solution of Oxalic acid or ethandioic acid can be used as a standard solution to standardise other alkali solutions because oxalic acid crystals are non-hygroscopic in nature. To prepare a 1 liter 1N solution of oxalic acid, follow these steps: 1. Carefully weigh 0.5 mol or 63 g of oxalic acid dihydrate crystals. This is because th n-factor of oxalic acid is 2 and so 1 mole of oxalic acid = 2 equivalents of oxalic acid. 2. Wash the 1 litre volumetric flask first with tap water (thrice), then with chromic acid solution (once but thoroughly) and finally with distilled water so as to remove any contaminants from the glassware. 3. Pour the crystals in the volumetric flask and add some distilled water. Shake the mix to dissolve the crystals in the solvent. 4. Make-up the volume to 1-litre by adding more distilled water.
What is the weight of oxalic acid?
Formula of oxalic acid is H2C2O4.2H2O. Therefore, the equivalent weight of the acid is molecular weight divided by n-factor = 126/2 = 63.

How do you prepare liquid of n-phenylanthranilic acid?
To prepare a solution of n-phenylanthranilic acid in a liquid form, you would typically dissolve the acid in a suitable solvent such as ethanol or water with the aid of gentle heating or stirring. The exact concentration of the solution will depend on the specific experimental requirements. It is important to handle the acid with care as it may be hazardous in its pure form.
How do you prepare 0.125 N sulfuric acid?
To prepare 0.125 N sulfuric acid, you would first need to calculate the amount of sulfuric acid needed by using the formula: (desired normality) x (equivalent weight) x (volume in liters) = mass of the substance. Then, weigh out the required amount of sulfuric acid and dissolve it in water to make the desired volume of solution.
How do you prepare 0.5 N acetic acid solution?
To prepare a 0.5 N acetic acid solution, first calculate the molarity needed using the formula Molarity (M) = Normality (N) x Equivalent weight. Then, use this information to dissolve the appropriate amount of acetic acid in water to make 1 liter of solution. Finally, adjust the volume with water as needed.
Where can oxcillic acid be purchased to clean rocks in San Antonio Texas?
A Marine store if you have one. Mail order from West Marine. 9.95 http://www.westmarine.com/webapp/wcs/stores/servlet/SiteSearchView?catalogId=10001&Ntx=mode+matchallpartial&keyword=oxalic+acid&Ntt=oxalic+acid&N=377+710&y=0&x=0&storeId=10001&Ntk=Primary+Search&ddkey=SiteSearch
How do you prepare 0.5 N sulphuric acid?
To prepare 0.5 N sulfuric acid, you can mix 49 g of sulfuric acid (H2SO4) into enough water to make 1 liter of solution. This will give you a solution that has a concentration of 0.5 N, meaning it contains 0.5 moles of H2SO4 per liter of solution. Remember to always add acid to water slowly while stirring to avoid splashing and to ensure a safe preparation process.
