Diet should be ideally 80% alkali and 20% acidic. But it is generally the other way around
Actually, it's both. It's got a basic hydroxyl group sticking out there, and an acidic hydrogen on that Nitrogen atom. But not very strong one way or the other...
This solution may be toxic, corrosive or radioactive.
The best way to find the strength of an acidic solution is to test it with a pH indicator. This can tell you the pH of the solution, which indicates the relative strength of the acid. Acids have a pH of below 7. The lower the number, the more acidic the solution is.
The addition of water can affect the acidity of a highly acidic solution in one major way. This addition will bring the pH up closer to 7.
Adding water to a highly acidic solution with a pH of 2 will dilute the solution, increasing the pH and making it less acidic. This is because water will act as a neutral substance, reducing the concentration of H+ ions in the solution and therefore raising the pH level towards neutrality.
acidic or basic and this is depending on what color it turns. If the unknown solution falls below 7 on the pH scale, then it is acidic but if it is more than 7 then it is basic. But if it falls straight on 7 then it is neutral. :)
The strength of an acidic solution is determined by its pH value. Lower pH values indicate stronger acidity, while higher pH values indicate weaker acidity. A strong acidic solution will have a low pH, typically below 3.
One way to distinguish between ethene and ethyne is by performing a bromine water test. Ethene will decolorize bromine water, turning it from orange to colorless, while ethyne will not react with bromine water. This test takes advantage of the unsaturation in ethene that allows it to quickly react with bromine.
It depends on the concentration of H+ ions in the solution. The more H+, the stronger it is. The best way to determine this is by its pH level, where a lower level means a stronger acid.
The H3O+ concentration in a solution with pH 3.22 = 1x10^-3.22 M or 6.03x10^-4 M.If a solution is 100 times less acidic, then the H3O+ concentration will be 6.03x10^-6 M.Put another way, 100 times less acidic will have a pH of 5.22 and H3O+ = 1x10^-5.22 = 6.03x10^-6M
Neutralisation is a chemical reaction between an acid and a base that results in the formation of water and a salt. It is a common way to balance the pH levels of a solution. In the process, the acidic and basic properties of the initial substances are canceled out, leading to a neutral outcome.
