electron. These are the three subatomic particles that make up an atom and their characteristics. Essay- Buffer System Buffers resist pH fluctuations. A buffer is composed of a weak acid and a weak base. Carbonic acid is the weak acid and bicarbonate is the weak base. When a solution is to acidic the pH is low and there are to many hydrogen ions. The low pH level is caused by to many hydrogen ions. To make a solution neutral you would need to make more acid my combining bicarbonate and hydrogen

problem of potentially hazardous chemicals. In addition‚ the impacts of pH‚ salinity‚ sodium‚ phoshphorus and sulphur are not addressed in advertising. Moreover‚ most product labels do not state the ingredients meaning that purchasers can never be sure what is actually in the product. Considering these issues‚ this project has been set out to analyse the effect of the greywater irrigation by addressing several factors such as the pH‚ salinity‚ electrical conductivity‚ hydraulic conductivity‚ surface

Chung Blanche Ely High School Abstract The researcher conducted this experiment in order to investigate how various factors effected enzymes. Those factors were the concentration of the enzyme‚ the temperature it had to work in‚ and the pH level of the solutions as well. All three were hypothesized to speed up the rate at which the enzyme acted. A series of several tests were carried out to find the answer to each problem. First‚ the scientist witnessed the enzyme diastase work in a natural

contained in rock which is exposed to air and water. The major components of ARD formation are reactive sulfide minerals‚ oxygen‚ and water. Biological activity and reactions is what is responsible for the production of ARD. These reactions make low pH water that has the ability to mobilize heavy metals contained in geological materials with which it comes in contact. "ARD causes a devastating impact on the quality of the ground or surface water it discharges to. (Ellison & Hutchison)" ACID MINE

Phenolic yellowing issues We have been facing yellowing on the fabrics kept at stores‚all the test results were passing like PH‚Phenolic yellowing‚Formaldehyde‚Light and BGF but we couldn;t come to an solution .Hence we have finally kept the fabric exposed in sunlight for a day and found that it has totally became yellow in the exposed area.So please advise whether the fabric stored can be wrapped with a opaque cover and also in the dark room to avoid the issue. 1 month ago * Close viewer
