A mixture of NaOH and NaHCO3 is incompatible because they share a cation. They both have Na+, so only the HCO3- and OH- will react. This leaves the products H2CO3 and NaOH.
Salicylic acid is soluble in NaOH and insoluble in NaHCO3 and HCl. In NaOH, salicylic acid can form a salt through neutralization. In NaHCO3 and HCl, salicylic acid remains as a solid due to its low solubility in these solutions.
When carbon dioxide is added to water containing sodium hydroxide carbonate ions are formed but the excess of carbon dioxide produces bicarbonate ions on evaporation a mixture of sodium carbonate and sodium bicarbonate is obtained.
Although we don't know the exact pH because we don't have any concentrations we know that NaHCO3 is a weak acid, and NaOH is a strong base. Thus we should get a solution that becomes more basic so the pH > 7.
Sodium hydroxide in a pure form is a solid, so you cannot dissolve anything in it. Normally, NaOH is used as an aqueous solution. But salicylic acid dissolves in water, so the presence of NaOH in the water is irrelevant to the solubility of salicylic acid. It is the water, not the NaOH, that dissolves the salicylic acid.
HCl + NaOH = NaCl + H2O Acid + Base = Salt + Water
NaHCO3 + H20 ---> NaOH + H20 + CO2

Sodium bicarbonate (NaHCO3) is a compound, not a mixture.
Sodium Hydroxide - NaOH Ammonia - NH3 Sodium Bicarbonate- NaHCO3 By Ruwayda
The compound NaHCO3 is also known as Sodium bicarbonate this often appears in very fine powder like baking soda. It has can be lactose that is found in milk to considered to be soluble with NaHCO3.
Although we don't know the exact pH because we don't have any concentrations we know that NaHCO3 is a weak acid, and NaOH is a strong base. Thus we should get a solution that becomes more basic so the pH > 7.
Sodium bicarbonate is a pure substance.
The chemical equation for the reaction between sodium hydrogen carbonate (NaHCO3) and limewater (Ca(OH)2) is: NaHCO3 + Ca(OH)2 → CaCO3 + NaOH + H2O This reaction produces calcium carbonate (CaCO3), sodium hydroxide (NaOH), and water (H2O).
It doesn't need balancing - it's already balanced. NaHCO3 + NaOH → Na2CO3 + H2O
No because you have an extra H. Sodium hydroxide is NaOH.
