What will happen to the ph of a solution of carbonic acid if sodium hydrogen carbonate is added?

when sodium hydrogen carbonate(NaHCO3) is added. The pH will increase, or become more basic.

Explanation:

Step 1: Data given

The solution contains carbonic acid = H2CO3

H2CO3 is a weak acid.

We'll add sodium hydrogen carbonate = NaHCO3

Step 2: What will happen to the pH

When we add NaHCO3, there will be formed a buffer of H2CO3/HCO3-

pH = pka+log ([A-]/[HA])

pH = pka+log ([HCO3-]/[H2CO3])

When NaHCO3 is added, [HCO3-] will be greater.

When [HCO3-] will be greater, ([HCO3-]/[H2CO3]) will be greater

When ([HCO3-]/[H2CO3]) will be greater, the pH will increase.

This means when sodium hydrogen carbonate(NaHCO3) is added. The pH will increase, or become more basic.

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error
