Select the value in column 3 corresponding to the volume of water into which the tablet is to be dissolved.Column 2 shows the maximum amount of hydrogen gas which can be produced from the tablet (under ideal conditions), based on the reaction stoichiometry and molecular weights.Select the value in column 1 corresponding to the amount of magnesium in your tablet, usually found on the label (if using two tablets, double the results shown in columns 2,5 & 6).Some tablet sizes, container volumes, and dissolved H 2 percentages: Of measured PPM and ingestible H 2 one can expect based on Table 1 below shows the maximum H 2 production possible, and the levels Ingestible H 2 will not necessarily be less. While a larger container will produce lower PPM readings, the amount of The temperature of the water - H 2 will dissolve better in cold water.(hours) is generally better than less time (minutes) The amount of time the tablet is permitted to dissolve - more time.Materials from which the container is constructed - less-porous.Whether or not the container can maintain pressure - pressure helps H 2 Given tablet size, these variables include: Percentage of H 2 gas which ultimately dissolves into the water. A few variables come into play which have an impact on the Only DISSOLVED H 2 can be considered (regardless of how much H 2 is When calculating ingestible H 2 levels, it is important to remember that Approximate the maximum level of dissolved H 2 (PPM) and ingestible H2.Calculate the theoretical maximum amount of H 2 which can be produced.Utilizing the number of milligrams of Magnesium contained in the tablet, Calculating the Theoretical Maximum Amounts of H 2 which can be We must relate the test sample to the size of the container from which it was taken to know how much H 2 will be ingested when the water is consumed. From this example, it can be seen that PPM's DO NOT tell the entire story about how much H 2 will be ingested when drinking the H 2 water being sampled. As the volume of water is halved, so too is the amount of dissolved H 2, resulting in the SAME concentration in each container. But, these containers DO NOT contain the same AMOUNT of dissolved H 2. In this example, a 6ml sample taken from each container will measure the same, 1PPM (10 drops of H 2Blue). The following graphic illustrates this concept: This is because it takes fewer milligrams of H 2 to produce 1PPM in smaller amounts of water than it does in 1 liter of water. In order to calculate the amount of ingestible dissolved H 2 present in a given container using the H 2Blue PPM reading, the size of the container into which the tablet was placed (and from which the 6ml test sample is taken) must be taken into consideration.

Only the dissolved H 2 gas can be considered when calculating ingestible H 2 levels.Ĭonverting the Amount of Ingestible H 2 based on PPM Reading and Container Size: This percentage can be influenced by factors such as temperature, time & pressure. The percentage of H 2 produced which actually dissolves into the water is typically in the 25% to 50% range. This is because a portion of the H 2 gas will escape into the air and be wasted. Although the theoretical maximum amount of H 2 gas which can be produced from one tablet (under ideal conditions) can be calculated based upon the amount of magnesium in the tablet (usually indicated on the label), not all of the H 2 gas produced will actually dissolve into the water. The production of the gas bubbles can be easily observed when placing a tablet in a clear container, and in a closed container, the pressure will rise as the volume of H 2 gas produced increases.ĭistinguishing Between "Produced" and "Dissolved" Hydrogen Gas:īecause each tablet contains a fixed amount of magnesium metal, usually in the range of 50 to 80 milligrams, the total amount of H 2 gas which can be produced from each tablet is also fixed. Hydrogen tablets produce hydrogen gas through the reaction of elemental magnesium (Mg) and water:
