Product reactions results. Tell if a chemical reaction or physical reaction occurs when mixing these two substances.
NaCL+ Distilled water =
NaCL+ Vegetable oil=
NaCL+ Vinegar=
NaCL+ Citric acid=
NaCL+ NaOH=
I know what happens when a chemical reaction and physical reaction occurs I just need help with this NaCL substance
thank you :)
NaCl is table salt
none of those give a chemical reaction.
To determine if a chemical or physical reaction occurs when mixing the given substances with NaCl (sodium chloride), it is important to understand the properties and characteristics of the substances involved.
1. NaCl + Distilled Water:
When NaCl (a solute) is mixed with distilled water (a solvent), a physical reaction occurs. This is known as dissolution or dissolving. NaCl will dissociate into its ions, Na+ and Cl-, which are then surrounded by water molecules due to their polar nature. This process is reversible and does not involve any chemical changes.
2. NaCl + Vegetable Oil:
When NaCl is mixed with vegetable oil, a physical reaction occurs. Oil is nonpolar, whereas NaCl is polar. Since like dissolves like, the polar NaCl and nonpolar vegetable oil do not mix. The mixture will separate into two distinct layers without any chemical changes.
3. NaCl + Vinegar:
When NaCl is mixed with vinegar (dilute acetic acid), a chemical reaction occurs. The acetic acid (CH3COOH) in vinegar reacts with NaCl to form sodium acetate (CH3COONa) and hydrogen chloride (HCl). This is an example of a neutralization reaction. The resulting sodium acetate remains in solution, while HCl is released as a gas, which can be perceived by its characteristic smell.
4. NaCl + Citric Acid:
When NaCl is mixed with citric acid, a chemical reaction occurs. Similar to the reaction with vinegar, the citric acid (C6H8O7) reacts with NaCl to produce sodium citrate (Na3C6H5O7) and hydrogen chloride (HCl). This is also a neutralization reaction in which sodium citrate remains in solution, and HCl is released as a gas.
5. NaCl + NaOH:
When NaCl is mixed with sodium hydroxide (NaOH), a chemical reaction occurs. The reaction is a double displacement reaction, resulting in the formation of sodium chloride (NaCl) and water (H2O). This reaction is also known as a neutralization reaction, as sodium hydroxide is a strong base and hydrochloric acid is formed from the reaction.
In summary, when NaCl is mixed with distilled water or vegetable oil, physical reactions occur. However, when NaCl is combined with vinegar, citric acid, or NaOH, chemical reactions occur.
