What is the difference between nitrate and chloride




















In addition, voltage-clamp measurements were made on short lumbricalis muscle fibers. KCl or KNO3 were added to the sulfate solutions and the fibers were equilibrated in these new solutions. When finally equilibrated the fibers had the same volume they had in the sulfate solutions before the additions. Constant hyperpolarizing voltage pulses of 0. For these conditions, inward currents flowing during the voltage pulses were largely carried by Cl- or NO3- depending on the final equilibrating solution.

Cl- currents during voltage pulses were both external pH and time dependent. Carbon dioxide gas bubbles if carbonate ions are present. Limewater is used to confirm that the gas is carbon dioxide. It turns from clear to milky when carbon dioxide is bubbled through. Sulfate ions in solution, SO 4 2 - , are detected using barium chloride solution.

The test solution is acidified using a few drops of dilute hydrochloric acid, and then a few drops of barium chloride solution are added. A white precipitate of barium sulfate forms if sulfate ions are present. For example:. The hydrochloric acid is added first to remove any carbonate ions that might be present - they would also produce a white precipitate, giving a false positive result. Barium nitrate solution can be used instead of barium chloride solution.

Sodium chloride is the compound that is responsible for the characteristic taste in seawater. The formula weight of sodium chloride is Sodium chloride is white when it is pure.

It appears as transparent or translucent cubic crystals. The melting point of sodium chloride is o C, while the boiling point is o C. It is well soluble in water. In the crystal structure of sodium chloride, each ion is surrounded by six ions of opposite charge.

These ions are located in a regular octahedron structure. Sodium chloride is hygroscopic. That means, it can absorb water vapour from the air when exposed to the atmosphere.

Besides, this compound is essential for us to maintain the electrolytic balance in our body. It is also used to preserve some food items. Sodium nitrate is an inorganic compound having a sodium cation and nitrate anion. It has the chemical formula NaNO 3. It appears as a white-colourless crystalline solid.

It is an alkali metal nitrate salt, which is named as Chile saltpetre in mineralogy.
