You'll need to know two things: what is the concentration of butyric acid you are starting with and how much 1 M butyric acid you want to end up with. From this, you can calculate how much water you need to add to a given volume of concentrated butyric acid to make 1 M butyric acid.
distill it from butter
30 grams
You would dissolve 1 part HNO3 into 99 parts of your solvent.
1 gram Oxalic Acid in 7 ml of water at room temperature - 1 gram per 2 ml of hot water will provide saturated solution.
In order to prepare 500 ppm of lead solution from lead nitrate dissolve 0.799 gm of lead nitrate in 1000ml of water--add 1 or 2 drops of nitric acid.
To prepare a 3% acetic (ethanoic) acid solution, you must first standardise the ethanoic acid. This question assumes that has already been done. To make the concentration 3%, there must be 30g per 1000mL (30gL-1). Dissolve or mix in 30g of ethanoic acid per 1000ml (1L). Pipette this into aliquots of 100mL samples. You now have a 3% ethanoic/acetic acid solution.

To prepare a 0.1 N glacial acetic acid solution, calculate the required mass by multiplying 0.1 moles by the molar mass of glacial acetic acid (60.05 g/mol). Weigh out the calculated mass and add it to a clean container. Dissolve the glacial acetic acid completely by stirring it with distilled water. Transfer the solution to a 1-liter volumetric flask and dilute it to the 1-liter mark with distilled water. Mix thoroughly, label, and store the solution properly, taking necessary safety precautions when handling glacial acetic acid.
Butan-1-ol, which is a primary alcohol, will be oxidised to butanoic acid. Butan-2-ol, which is a secondary alcohol, will be oxidised to butanone.
The molecular formula for butyric acid is C4H10O2. The formula shows that the number of hydrogen atoms in each molecule is 10 and the number of oxygen atoms in each molecule is 2 The proportions between two elements in a compound are the same as those in a single molecule: 10:2, which can be simplified to 5:1.
hehehe
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.
Preparation of standards Prepare a stock uric acid solution of 100 mg/L. Dilute it to give working concentrations of 10, 20, 30, 40, 50 and 60 mg/L. Procedure:1 Prepare a 100 mg/L stock solution of uric acid Weigh out 100 mg uric acid, transfer it to a 1 L volumetric flash, add about 900 ml distilled water, and then add about 100 µl of 0.6 N NaOH to help dissolve the uric acid. Make up to the volume with water when uric acid is fully dissolved.2 Dilute the stock solution to give working concentrations of 10, 20, 30, 40, 50, 60 mg/L. To prepare 50 ml of the working standards 5, 10, 20, 30, 40, 50 mg/L respectively, weigh 10, 15, 20, 25, 30 g of stock solution into 50 ml volumetric flasks and make up to volume with distilled water.
Hydrochloric acid as this acid disassociates fully in solution while ethanoic acid is a weak organic acid that disassociates at only about 1% in solution.
