In which glass of water does the effervescent tablet dissolve faster Why?
In the hot water the tablet should have more vigorously produced bubbles than in the cold water. The higher the temperature, the faster the molecules move—and the more likely it is that the bicarbonate will contact hydrogen in just the right way for the chemical reaction to occur and produce carbon dioxide bubbles.
Do crushed tablets dissolve faster than whole tablets?
The crushed tablet fizzes faster than the whole tablet. That’s because it has a greater surface area to volume ratio. That means that for the same amount of antacid (one tablet), there is more surface—or exterior—to react with the water. Small things have a greater surface area to volume ratio than larger things do.
Why does crushed tablet react faster than whole tablet?
The smaller the pieces of the tablet the faster it fizzes because the smaller pieces have more surface area. For the same amount of antacid, the crushed tablet has more surface, or exterior, to react with the water. Since the water can reach more of the tablet immediately, the reaction, or fizzing, happens faster.
Why does powder react faster?
The more concentrated the faster the rate (note in some cases the rate may be unaffected by the concentration of a particular reactant provided it is present at a minimum concentration). Powders react faster than blocks – greater surface area and since the reaction occurs at the surface we get a faster rate.
Which reaction is faster?
Reactions in phases that easily mix, such as gases and liquids, occur much faster than reactions between solids. The extent of mixing of the reactants influences the frequency of molecular collisions – if reactants are more thoroughly mixed, the molecules will collide more often and thus react faster.
Do effervescent tablets dissolve faster in hot water?
As a result of the experiment, the hot water caused the Alka-Seltzer tablets to dissolve about 2 times quicker than water at lukewarm temperatures, and about 3 times faster than water at a cold temperature.
What makes a tablet dissolve faster?
The more surface area (or exposed area) results in more sites that contact water immediately, resulting in the antacid dissolving faster and the chemical reaction (fizzing) happening faster. The crushed tablet has the smallest pieces and thus the highest surface area to volume ratio, causing it to react the fastest.
Why does powder dissolve faster than solids?
A given quantity of solute dissolves faster when it is ground into small particles than if it is in the form of a large chunk because more surface area is exposed. The packet of granulated sugar exposes far more surface area to the solvent and dissolves more quickly than the sugar cube.
Why do powders react more quickly than crystals?
A powdered solid will normally produce a faster reaction than if the same mass is present as a single lump. The powdered solid has a greater surface area than the single lump.
Why does powdered zinc react faster?
Powdered zinc has greater surface area exposed to hydrochloric acid. Generally, as particle size decreases, surface area increases, and reaction rate also increases.
Why do aqueous solutions react faster?
Reactions between ions in solutions tend to be fast because of they are close to each other and they are free to move around. In general the rate of reaction goes as aqueous ions > gases or liquids > solids.
