They are two completely different substances Sodium nitrate is NaNO3, a compound of sodium, nitrogen, and oxygen. It is an inorganic salt and a strong oxidizer. It is sometimes used as a fertilizer or in black powder. There are 3 variants of sodium citrate: Monosodium citrate (NaH2C6H5O7), disodium citrate (Na2HC6H5O7), and trisodium citrate (Na3C6H5O7). All three are compounds of sodium, hydrogen, carbon, and oxygen. They are organic salts commonly used as food additives.
Sodium phosphate is a white crystalline solid that is colorless or appears as a white powder.
The equation between potassium iodate (KIO3) and sodium thiosulfate (Na2S2O3) involves a redox reaction. In the presence of an acid, potassium iodate is reduced to iodine (I2), while sodium thiosulfate is oxidized to form sodium tetrathionate (Na2S4O6). The balanced chemical equation for this reaction is 5Na2S2O3 + 2KIO3 + 8HCl → 5Na2S4O6 + 2I2 + 2KCl + 6H2O.
When copper II hydroxide and sodium nitrate are heated together, they may undergo a decomposition reaction. Copper II hydroxide will decompose into copper II oxide and water, while sodium nitrate will decompose into sodium nitrite and oxygen.
When you heat copper hydroxide and sodium nitrate, a chemical reaction occurs where the copper hydroxide decomposes to form copper oxide and water, while the sodium nitrate decomposes to form sodium nitrite, oxygen gas, and nitrogen dioxide gas.
The color change occurs because iodine reacts with starch to form a blue-black complex. Initially, the iodine reacts with the sodium thiosulfate until it is completely consumed, resulting in a color change from yellow to brown. Once the sodium thiosulfate is depleted, any excess iodine present reacts with the starch indicator, causing the solution to turn blue-black, indicating the endpoint of the titration.
In Fixer you can find Sodium thiosulfate :Na2S2O3·5H2O and Ammonium thiosulfate: (NH4)2S2O3 for black and white photography, in purpose to remove unexposed silver halide.They can not be found in developer ! In Developer for black and white photography: Metol,Phenidone and Hidroquinone for purpose chemical that makes the latent image on the film or print visible!
Thiosulfate in the triple sugar iron agar acts as a sulfur source and helps to detect hydrogen sulfide production by bacteria. It can also serve as a reducing agent to maintain anaerobic conditions in the medium.
Phenolphthalein is an acid base indicator - it does not show the end-point in a thiosulfate type titration. Starch gives a very sharp end-point from a blue-black to colorless end-point when titrating iodine with thiosulfate. Phenolphthalein would just not detect this change.
Starch forms a blue-black complex with iodine, making it easy to see when the iodine has been fully neutralized in the titration. The color change is very distinct, allowing for accurate endpoint determination in the titration process.
The reaction between H2SO4 and HCl gives you Sulphurous Acid (H2SO3). A quick test for H2SO3 is to blot filter paper with starch solution, then add iodine to give a blue/black stain. In the presence of H2SO3 this stain will be bleached.
There will be no reaction. It will remain a mixture.
compound
Well...depends who you ask :P. I guess two. Sodium Chloride is NaCl. It's an "ionic compound" which means the atoms are not covalently bonded, they actually exist as Na+ and Cl-. At this point, it's worth mentioning that an ion is any charged species. Positive or negative, they're both ions. The reason it's a bone of contention is because bonding is not black and white. Covalent or ionic...it's a sliding scale and you can't just say where one begins and the other ends. That said, it is widely accepted that NaCl is a highly ionic bond.

compound
The "T" in Eriochrome Black T stands for the word "Tetrasodium," indicating that this compound contains four sodium atoms in its structure. Eriochrome Black T is a complexometric indicator commonly used in analytical chemistry for the determination of metal ions.
