Sodium oxalate also acts as primary standard used for standardizing the solution of potassium permanganate whose molecular formula is KMnO4. It is required that the temperature of titration mixture exceeds 60oC to make sure that all of the permanganate added to the mixture reacts rapidly.Sodium oxalate is prepared by neutralizing oxalic acid with sodium hydroxide (NaOH) in the acid-to-base ratio of 1:2. If the sodium hydroxide is half neutralized in 1:1, then sodium hydrogenoxalate or monobasic sodium oxalate is produced.Just like various other oxalates such as ammonium oxalate, etc., sodium oxalate is also highly poisonous to the humans. It can result in the burning ache in the head, mouth, stomach and throat. Sodium oxalate can also cause bloody vomiting, muscle cramps, fall in the blood pressure, coma, heart failure, shock, and in severe cases, death. The average toxic dose by ingestion of sodium oxalate is 10-15 grams. Like citrates, sodium oxalate also has the property of removing calcium ions from the blood plasma. It also inhibits blood from clotting. By doing this, it can hinder the function of the brain as well as calcium oxalate gets deposited in the kidneys.  So, we should always prevent our body from coming in contact with this element.

it's also advisable to have your pH readings checked by a medical professional. After a period of this treatment your blood uric acid levels can be checked to discover whether the potassium citrate and pH testing procedure is working to raise urine PH and the real objective which is to lower uric acid. If it's not, the potassium citrate dose can be adjusted upwards, or perhaps downwards if it is.Your doctor may want to consider other alkalizers such as potassium-magnesium citrate or potassium-sodium citrate which studies have shown also raise the pH of urine.The amount of potassium citrate required to raise urine pH is not likely to be found over the counter (OTC) or on those online vitamin websites which sell dietary supplements of potassium citrate. These products contain 99mg per tablet. Almost certainly you will need much more than this to deliver therapeutic benefits, which means prescription potassium citrate. Happily potassium is not expensive.NB. This article contains medical information, not medical advice. If you have gout, or hyperuricemia, always discuss dietary change with a doctor.
