Analysis Of Alka Seltzer Tablet Rate Of Reaction Lab Report

751 Words4 Pages

The topic the scientists will be conducting is called Alka-Seltzer Tablets, Rate of Reaction. Here the scientists will be testing the reaction time of Alka-Seltzer tablets. The scientists will be testing that by taking various substances and dropping in one Alka-Seltzer tablet per each cup of liquid. The scientists will be testing the variables include the temperature such as cold water, salt water at room temperature, room temperature water, vinegar water at room temperature that’s the independent variables. The dependent variable is the rate of dissolving in seconds. The constant would be the brand of Alka-Seltzer tablets and amount of liquid. Finally, is the control variable and here it would be the room temperature water with nothing added …show more content…

The scientists will conduct the experiment by taking four cups of water one that is just salt mixed with water, another that is just water, a third cup that is just ice water and finally a forth cup that is vinegar and water mixed. After that the scientists will drop one Alka-Seltzer tablet into each cup and see how long it takes for it to completely dissolve. The scientists will conduct these three times for …show more content…

Beneath Our feet Experiment 1: We put different types of rocks in to three piles that were called Igneous, Metamorphic and Sedimentary. Igneous comes from a volcano. Metamorphic is heat and pressure and Sedimentary is a mixture of conglomerate, fossils and layers. Experiment 2: We put chalk and 3 spoons of sand into a cup and shook it really hard. Some of the sand turned pink which was the colour of the chalk.

Research Question: To investigate and compare how different temperature (5℃, 15℃, 25℃, 35℃, 45℃) can affect the concentration of carbon dioxide in soda water through titration with sodium hydroxide solution. Introduction: Carbon dioxide plays an important role in soft drinks. Soda water is manufactured by pumping carbon dioxide into water under high pressure. Carbon dioxide dissolves in water to form carbonic acid, which is the fizz we find in soft drinks. CO2 + H2O ⇌

So I decided to learn the real science behind it. Another reason why I thought it would be cool to do this project is because I thought it would be cool if I did where I can substitute chemicals to inflate a balloon. So, I came up with the question which liquid can inflate a balloon faster. First Alexis is going to talk about the independent variable why and what substances Alexis will be using. The reason Alexis will be using.

The effect of the temperature on the reaction time of human hand responding to a sight stimulus Design Research Question: How does the temperature affect the reaction time of human hand in responding to a sight stimulus? Hypothesis: Temperature is an important factor in regulating blood supply and nerve signals. Lower temperatures decrease the nerve signals from brain to hand, thereby slow the reaction (Ascroft). When the hand is submerged in cold water, the sensory receptor nerves in the skin recognize the fall in temperature and send signals to the hypothalamus.

Inaccurate Timing Lab Report

1019 Words | 5 Pages

The effect of the random errors from this experiment might due to the inaccurate timing as the reflect time to stop the stopwatch when 30cm3 of carbon dioxide is collected in 100mL measuring cylinder is often various from time to time. Time may be longer or shorter than the actual time taken to collect 30cm3 of carbon dioxide. This will then lead to the wrongly calculation of the rate of reaction as the formula of the rate of reaction is: Rate of reaction=1/(Time taken to collect 30.0cm³ of carbon dioxide (s)) Next, the sources of the random errors in this experiment are the variation in eye level when taking the readings of a measuring cylinder to collect 30cm³of carbon dioxide and the widely spaced graduation mark on a 100mL measuring

We measured the elapsed time of bubble production in seconds as the dependent variable, and used the condition of the tablets as the independent variable. The control is the amount of Alka-Seltzer and the water temperature. One tablet was used in all the beakers and the water was all the same temperature. The results showed the the tablets with greater surface area dissolved faster than their peers. The quartered tablets bubble production (54.77 secs) was faster than the whole tablets (77.32 secs), while the crushed tablet’s bubble production (27.28 secs) was faster than the quartered tablets.

Hot Water Vs Cold Water Essay

1472 Words | 6 Pages

Abstract— “An explanation for why hot water will sometime freeze more rapidly than cold water is offered. Two specimens of water from the same source will often have different spontaneous freezing temperatures; that is, the temperature at which freezing begins. When both specimens supercool and the spontaneous freezing temperature of the hot water is higher than that of the cold water, then the hot water will usually freeze first, if all other conditions are equal and remain so during cooling. The probability that the hot water will freeze first if it has the higher spontaneous freezing temperature will be larger for a larger difference in spontaneous freezing temperature. The keys to observing hot water freezing before cold water are supercooling the water and having a significant difference in the spontaneous freezing temperature of the two water specimens”.
