What happens when you mix sodium chloride and sodium bicarbonate?

SODIUM BICARBONATE+SODIUM CHLORIDE both are sodium salts. Both of the salts work together to provide moisture in the nasal cavity so that the thick mucus softens. This, in turn, helps to clear out the mucus from the nose and relieves the nasal (nose) blockage.

What happens when you mix sodium bicarbonate and phenol red?

Sodium bicarbonate is a base, so it maintains the bright red (basic) color of phenol red at first. As sodium bicarbonate reacts with calcium chloride in water, acidic substances are produced and the color of the phenol red indicator changes from the basic form to its yellow, acidic form.

Is the color change of calcium chloride sodium bicarbonate and phenol red physical or chemical?

Raquel: The road salt, baking soda, and phenol red solution resulted in chemical reaction. I know this because the mixture changed color and temperature and it also formed a gas and a solid. This is evidence of a chemical reaction, meaning new substances were made.

What is the chemical reaction in a Ziploc bag?

The bag fills with carbon dioxide gas because the hydrogen ion (formed by ionization of bicarbonate) reacts with remaining bicarbonate ion to give carbon dioxide gas. There will be cold and hot spots, and finally the bag continues to feel cold because heat is being absorbed. See equation below.

What is the reaction in a bag of phenol red?

The chemicals react to form calcium carbonate, sodium chloride, and carbon dioxide gas. This changes the pH inside the bag resulting in a color change in the phenol red. As much air as possible should be removed from the bag as possible to show the production of the gas.

Is mixing phenol red and baking soda a chemical change?

Description: This video shows a chemical reaction of sodium bicarbonate (baking soda), calcium chloride (road salt), and an indicator phenol red. The chemicals react to form calcium carbonate, sodium chloride, and carbon dioxide gas. This changes the pH inside the bag resulting in a color change in the phenol red.

What happens when you mix phenol red and calcium chloride?

(2) When the phenol red solution was added to the baking soda/calcium chloride bag, the color started changing from red to yellow (some students may say they saw some pink color accept this as well.)

What compounds react with sodium bicarbonate?

Sodium bicarbonate reacts with acetic acid (found in vinegar), producing sodium acetate, water, and carbon dioxide: NaHCO3 + CH3COOH CH3COONa + H2O + CO2(g) Sodium bicarbonate reacts with bases such as sodium hydroxide to form carbonates: NaHCO3 + NaOH Na2CO3 + H2O.
