Why Do Children's Multivitamins Dissolve
100 Words1 Pages
My hypothesis for this question is that the children 's multivitamin will dissolve differently when placed under different water temperatures.I predict that the multivitamins will dissolve very fast when placed in the hot water ( in this experiment 100°C), and will dissolve very slowly when placed in the ice cold water (in this experiment, 0°C).My prediction is based on alot of things that are dissolvable.Dissolve more quicker in hot water than cold water as it has more concentration.

To accurately determine this, each trial will have recorded dependent and independent variables, constants and a control. The hypothesis being researched, indicates higher temperatures allow for a rapid rate of dissolution. In this particular case with someone needing Alka Seltzer, they will feel better faster if they use hot water to dissolve the medicine before

Identify the independent Variable Size of the tablet Identify the dependent Variable Reaction time List the controlled variables The solution (water), temperature, volume of water (200 mls) The amount of Alka- Seltzer How will the dependent variables be measured A stop watch will be started as the pieces of Alka-Seltzer are dropped into 200ml of room temperture water Describe the expected results if the hypothesis is true The 3 smaller pieces of Alka Seltzer will dissolve quicker than the ½ tablet .

In this particular experiment the constant condition, the factor that was never changed, was the room temperature water. The independent variable, the variable the student affected, was how much water was placed into the beakers. The dependent variable, a variable that was affected by the independent variable, was the time it took for the tablet to fully dissolve. The control group, which did not receive treatment from the students, was the 50 ml of water as a result of being the medium between the three measurements of water. Finally, the experimental group, the subject that was exposed to the variable during the experiment, was the 25 ml and 75 ml of
How does the type of dissolvent in the water affect the number of drops that can fit on a penny? We will attempt to find the answer to this question using the hypothesis “If we use salt water solution, then there will be more drops on the penny. ” We will use the materials salt, sugar, lemonade mix, flour, a beaker, a pipette, paper towels, a stirring rod, a graduated cylinder, and some tap

The dissolution of the salt could be reversed by evaporating the water as shown in part one of the experiment, just as evaporating the water could be reversed by adding water as demonstrated in part two of the

There are two types of vitamins: water soluble and fat soluble. Water soluble vitamins include vitaminsB1, B2, B3, B6, B12, vitamin C, biotin and folate. They are not stored in large amounts in the body, andany extra is lost through your urine says the Dietitians of Canada web page. Vitamin B1 helps with energy production in the body. Vitamin B2 helps with energy production in thebody.

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 ⇌

In this lab we used two processes called Diffusion and Osmosis. Diffusion is the movement of molecules from areas of high concentration to areas of low concentration. Diffusion is a process that requires no energy and involves smaller non-polar molecules. In Figure 1 you can see the molecules spreading throughout the glass from the area of high concentration, so that the areas with low concentration are filled evenly as well. The other process was osmosis.

Introduction The intent of this experiment is to understand how hot and cold water interact with each other by combining clear hot water and black ice cold water. I hope to learn more about how hot and cold water interact with each other. As of now, I know that cold water is denser than hot water. Knowing this I formed my hypothesis.

When temperature is increased, the amount of obtainable energy increases; meaning that particles will move at faster pace at a higher temperature. Thus rate at which molecules diffuse will progressively speed up as the temperature increases. However if temperature of solution is decreased the rate of osmosis will decrease and rate at which molecules diffuse will be significantly less than that of higher

Top Health Benefits Vitamin B12 Top Health Benefits of Vitamin B12 Best Health Tips for Vitamin B12 Vitamin B12, also known as cobalamin, is a water-soluble vitamin that plays a key role in the normal functioning of the brain and nervous system and in blood formation. It is one of eight vitamins. It is usually involved in the metabolism of human cells, in particular, affect the synthesis and regulation of DNA, but also related to fatty acid synthesis and energy generation. As the largest and most structured vitamins, it can only be produced industrially through bacterial fermentation-synthesis. Vitamin B12 is essential for the normal functioning and health of red blood cells and nerve tissue.

Rickets is the softening and weakening of bones in children, because of an extreme and extended vitamin D deficiency. It is highly unhealthy. Symptoms of rickets include: Bone pain or tenderness in arms, legs, pelvis and the spine. There may also be dental deformities, such as delayed formation of teeth decreased muscle tone, (loss of muscle strength), defects in the structure of teeth; holes in the enamel, and increased cavities in the teeth (dental caries). There could also be progressive weakness, impaired growth, increased bone fractures, muscle cramps, and short stature, (adults less than 5 feet tall)

You are given a known solid substance with its melting point which has high solubility in hot water and low solubility in cold water. You are assigned the following task: i. Determine if the substance is pure ii. If impure, find a suitable method for its purification by using the given information about the substance How would you proceed, clearly explain your rationale? i. To find if it is a pure substance we see if there is a change in melting point. ii.

Introduction Solubility is a chemical property that is measured in terms of the maximum amount of solute dissolved in a solvent at equilibrium. The resulting solution is called saturated solution. For example when a sample of sodium chloride solution in water is heated the behavior of the reaction is endothermic obstructing exothermic behavior. Another relationship that can be said about solubility is that the solubility of a solid substance increases as the temperature increases. The solubility of solutes is dependent on temperature.
