11 Zinc reacts with an excess dilute hydrochloric acid. The graph shows how the volume of hydrogen gas given off changed with time.Volume of hydrogen XTime0Why does the graph become horizontal at X?B A All the dilute hydrochloric acid has been reacted. B All the zinc has reacted. C Hy...
To dilute an aqueous solution, you simply add water to it. This increases the proportion of the solvent or the liquid material for dilution compared to that of the solute or the component dissolved in the solvent. For example, if you dilute saltwater, the solution will contain the same amoun...
wounds and inflammations. Harvest just when the buds began to open on a sunny day. To tell if they are ready, press a bud between your fingers, if there’s a spurt of purple or deep red they are ready to pick, if not it is either too early or too ...
You may use the following information to help you.. copper(Il) chloride is soluble in water. copper metal does not react with dilute acids..[5](b)E Ethanol can be used as a fuel for vehicle and other machines.(i) Name the process by which ethanol is made from glucose.[1](ii) ...
Natural stains (as well as dyes) produced by everything from mildew to grass come from chemical compounds called chromophores. Chromophores can absorb light at specific wavelengths and therefore cause colors. When chlorine reacts with water, it produces hydrochloric acid and atomic oxygen. The oxygen...
Pour it down the sink with copious amounts of water. The ice does two things. It dilutes the aqua regia as it melts and takes up the heat of dilution that is generated when aqua regia is diluted. Leaving it overnight and allowing the nitrosyl chloride to break down is tantamount to ...
-Hydrochloric acid (same thing as as muriatic acid) -Hydrogen peroxide (same thing as oxygenated water) -A shallow plastic container to mix the peroxide with the acid (2:1 mix, depending on the peroxide concentration you may need to change the mix, I used 11vol. peroxide) ...

Hydrochloric acid was added as vapour and sulphuric acid as a dilute aqueous solution and the fibres subsequently air-dried. The acid-aged fibres became more digestible to rumen fluid (in vitro) and to cellulase, with improvements up to four-fold (for 1.1% hydrochloric acid in oat hulls). ...
You will want to use 1 part Muriatic Acid per 20 parts water. Regarding the ratio,some recommend as much as 1:1, or as little a 1:29. In this case, I simply used one gallon of acid with as little water as needed to completely cover the filters - I estimate some 25 gallons. Reme...
