First of all, buffering your solution with sodium bicarbonate isn't strictly necessary although some people believe it makes the solution more pleasant to use.
The amount of baking soda (sodium bicarbonate) people use seems to vary, but as long as you don't have more baking soda than salt I think you should be fine.
Natron is not an element. It is a mixture of compounds: sodium carbonate decahydrate, sodium bicarbonate, sodium chloride and sodium sulfate.
Sodium bicarbonate (NaHCO3) is a compound, not a mixture.
Use of sodium chloride solutions or aerosols for nasal irrigation.
No sodium chloride is not a heterogeneous mixture.
Natron is a mixture of sodium carbonate decahydrate and around 17% sodium bicarbonate with small amounts of sodium chloride and sodium sulfate. Natron is naturally occurring.
NaCl (sodium chloride) is a compound, not a mixture.
Salted water is not used for irrigation in agriculture. Sodium chloride irrigation can be used for the nose disinfection etc.
Sucrose has the chemical formula C12H22O11. Sodium chloride has the chemical formula NaCl. Sodium bicarbonate has the chemical formula NaHCO3.
Sodium chloride is a compound, not a mixture.
No sodium chloride is not a heterogeneous mixture.
The mixture is extracted with the sodium bicarbonate to remove the excess acid. This will increase the pH.
Calcium Chloride and Sodium Bicarbonate turn pink, then turn yellow due to carbonic acid that is created. the mixture turns hot and gas is, about 10 seconds later the mixture stops producing gas and turns cold.
