Why is sodium oxalate added in fresh blood?
Sodium oxalate is added to fresh blood samples as an anticoagulant. It binds with calcium ions in the blood, preventing blood clotting by inhibiting the coagulation cascade. This allows the blood sample to remain in a liquid state for analysis.
How many ions present in NaCl solution?
In a NaCl (sodium chloride) solution, there are two types of ions present: sodium ions (Na+) and chloride ions (Cl-). This is because when NaCl dissolves in water, it dissociates into these two ions, which are responsible for conducting electricity in the solution.
What ions are present in sodium sulphate solution?
Dissolving in water (aq):Na2SO4 --> 2(Na+)aq + (SO42-)aq
What is the exact ratio of sodium ions to chloride ions in NaCl?
The ratio of sodium ions to chloride ions in NaCl is 1:1. This means that for every sodium ion (Na+) present, there is one chloride ion (Cl-) present.
What are the metal ions present in sodium chloride?
In sodium chloride (NaCl), there are no metal ions present. Sodium (Na) is a metal cation, and chloride (Cl) is a non-metal anion. When they combine to form NaCl, they do not exist as individual metal ions.

What is the product of NaC2O4 and Ag plus?
The product of sodium oxalate (NaC2O4) and silver ions (Ag⁺) is silver oxalate (Ag2C2O4), which is a sparingly soluble compound. In solution, two silver ions can react with one oxalate ion to form the precipitate. Sodium ions (Na⁺) remain in the solution as spectator ions. Thus, the overall reaction can be represented as NaC2O4 + 2Ag⁺ → Ag2C2O4 (s) + 2Na⁺.
What types of ions are presented in salt?
In salt, the common types of ions present are sodium (Na+) and chloride (Cl-). Sodium carries a positive charge, while chloride carries a negative charge, forming an ionic bond that makes up salt crystals.
Is any reaction is between oxalate ions and zinc ions?
No, oxalate ions and zinc ions do not react with each other in a typical chemical reaction. Oxalate ions are not strong enough reducing agents to displace zinc from its compounds.

Can starch abserve sodium ions present in water?
No, starch cannot absorb sodium ions present in water. Starch is a carbohydrate polymer and does not have specific binding sites for sodium ions. Other materials such as ion exchange resins or zeolites are commonly used to remove sodium ions from water.
Why you use the H2SO4 in sodium oxalate ion?
Disodium oxalate, often called simply sodium oxalate, is a sodium salt of oxalic acid with the molecular formula Na2C2O4. It is usually a white, crystalline, odorless powder, that decomposes at 250-270 °C.Disodium oxalate can act as a reducing agent, and it may be used as a primary standard for standardizing potassium permanganate (KMnO4) solutions.The mineral form of sodium oxalate is natroxalate. It is only very rarely found and restricted to extremely sodic conditions of ultra-alkaline pegmatites.[1]Contents[hide] 1 Preparation2 Reactions3 Biological activity4 ReferencesPreparationSodium oxalate can be prepared through the neutralization of oxalic acid with NaOH in a 1:2 acid-to-base molar ratio. Half-neutralization can be accomplished with NaOH in a 1:1 ratio which produces NaHC2O4, monobasic sodium oxalate or sodium hydrogenoxalate. ReactionsSodium oxalate is used to standardize potassium permanganate solutions. It is desirable that the temperature of the titration mixture is greater than 60 °C to ensure that all the permanganate added reacts quickly. The kinetics of the reaction is complex, and the manganate(II) ions formed catalyze the further reaction between permanganate and oxalic acid (formed in situ by the addition of excess sulfuric acid). The final equation is as follows:[2]5H2C2O4 + 2KMnO4 + 3H2SO4 → K2SO4 + 2MnSO4 + 10CO2 + 8H2O Biological activityLike several other oxalates, sodium oxalate is toxic to humans. It can cause burning pain in the mouth, throat and stomach, bloody vomiting, headache, muscle cramps, cramps and convulsions, drop in blood pressure, heart failure, shock, coma, and possible death. Mean lethal dose by ingestion of oxalates is 10-15 grams (per MSDS). Sodium oxalate, like citrates, can also be used to remove calcium ions (Ca2+) from blood plasma. It also prevents blood from clotting. Note that by removing calcium ions from the blood, sodium oxalate can impair brain function, and deposit calcium oxalate in the kidneys
When sodium sulfate dissolves in water what ion would be present in the solution?
When sodium sulfate dissolves in water, it dissociates into sodium ions (Na⁺) and sulfate ions (SO₄²⁻). These ions would be present in the solution along with water molecules.
What can be the viva questions on oxalate ions?
Oxalates are salts of oxalic acid containing oxalate ion. Oxalate ion is a dianion. Upon protonation, oxalate ion forms a commonly known compound, oxalic acid. The commonly known oxalate salts are sodium oxalate, potassium oxalate etc. The calcium metal ion reacts with oxalate ion to form an insoluble precipitate of calcium oxalate, which is the primary constituent of most of the common kind of Kidney stones.
