I can see how diamonds crushed into nano diamonds could essentially filter particles from water or other liquids. OK sounds good to me, so there is something to it. The problem is where I heard of this was from Dan Aykroyd who claims to use regular larger diamonds to filter water and that the diamonds have pours that suck up the impurities. I call ...

The pressure inside the can/bottle is higher than the atmospheric pressure and due to this higher pressure, the freezing point of the beer increases. When you opened the can/bottle, the pressure of the beer equals the atmospheric pressure, decreasing the freezing point of the beer and hence, starting to freeze. Cheers!

The Charlie Brown's Thanksgiving episode of Binging with Babish claims that the baking powder "lower[s] the temperature at which the Maillard reaction occurs." Wikipedia doesn't quite back that up but says that the Maillard reaction "is accelerated in an alkaline environment (e.g., lye applied to darken pretzels [...]), as the amino groups ($\ce{RNH3+ -> ...

The changed taste that stays after cooling the heated water Hot (boiling) water has a much lower capacity for dissolving gases. When boiling water, $\ce{CO2}$ is removed and through the equilibria behind ($\ce{CO2 + H2O <=> H2CO3}$ and $\ce{H2CO3 <=> H+ + HCO3-}$) so is $\ce{HCO3-}$. Basically, this removes $\ce{CO2}$, overall carbonic acid ...

Many of the components of gasoline (petrol) have notable odours A simple starting point for understanding the odour of gasoline is the typical composition of the product. That composition varies a lot and always has done as different refineries use different processing techniques and different crude oil sources have different components to start with. And ...

The refractometer is an elegant solution, indeed. Other option is to use a simple, home made, small container with water tight cap, with adjusted mass of e.g. fine sand or salt content to have container average density between both colas. You would adjust it to sink in diet cola and float in regular cola. Note that I am not a cola drinker,but I guess ...

Better than a hydrometer, use an Abbe refractometer to measure the index of refraction, which varies with sugar concentration. It requires just a drop of liquid, and that small sample is unlikely to have bubbles, reducing density. You can make a refractometer to measure the sugar concentration, or you can buy one for ~$US20. That said, diet sodas have been ...

I'm only a chemist by desire and curiosity but as a Practical Maintenance Engineer let me throw this out there. Galvanized steel is a really bad idea. Just about any commercial sheet metal is going to breakdown relatively quickly in your environment. Brass is the best of a bad list but, it too, will ultimately corrode. Find someone with a plastic ...

Gold has only one natural isotope: 197. There are artificial gold isotopes, but they do not end up in gold bars. Even if they did, their half life is measured in days so don’t expect much to remain after a year or so. The “structure” of the metal bar, or atomic arrangement, has nothing to do with its isotopic composition. Even if you were to measure ...

Experimental design also comes into the fray. If you have an apparatus that is not quantitatively accurate, you can apply it to your experimental ssmple and to a control for ccx which you have a reference value of what you are trying to measure. You then calibrate your results to the known reference. I've used this approach at work, to compare acid ...

To add to @Poutnik's and @M.Farooq's answers: Is there a good way to systematically increase the accuracy and precision of a measuring tool using only mathematical means? No, because what you can and should do in terms of maths/statistics depends very much on your application and data generation/measurement processes. Using only mathematical means is ...

Generally, improvement of measurement process has much better positive impact on results, than sophisticated mathematical processing of low quality data. But, sometimes we are forced to data what we have. There are 3 quantities: resolution = the smallest difference of directly measured value, distinguishable by the tool, precision = Level of uncertainty ...

Your non-trivial question has a yes and a no. It is not possible to increase the accuracy of a dataset just by mathematical means. If you knew the systematic error in your data then you can do the arithmetic to correct the error. There is no a priori way to ascertain if your measurement tool lacks accuracy until and unless we have a reference for comparison. ...

Calcium hypochlorite is supposed to be added to water. If a little water is added to the hypochlorite, it can start to oxidize and produce stronger chloric acid. The SDS says to avoid water and moisture. To test this, try adding just a few drops of water to a pile of powder or a pill and see if a reaction begins. Unless you have a vandal, it is not likely ...

Note that chlorine can be created just by adding water. $$\ce{Cl- + ClO- + H2O <=> Cl2 ^ + 2 OH-}$$ Enough $\ce{CO2}$ dissolved in wet tablets of calcium hypochlorite ( mixed calcium hypochlorite, chloride and hydroxide) would speed up the above, as it would release hypochlorous acid $\ce{HClO}$, which is weaker than carbonic acid. $\ce{HClO}$, ...

It is almost certain that the gas you saw was chlorine (Cl2). It is a VERY TOXIC gas, so stay away!! Hypochlorite releases chorine gas when pH is too low. That is why bleach must not be mixed with acid. Never! In this case it is probably Muratic (hydrochloric) acid that has been added to the hypochlorite in excess. The acid is used to adjust the pH in the ...

That’s true about the welded joint for two galvanized objects. The welded area needs to be galvanized after welding to provide the protective layer (anode). Depending on the solution in contact with the galvanized and time and temp you have varying degrees of protection. Galvanized pipes etc are ok in general weather but salt water for instance ...
