How does a solution with a pH of 7 compare to a solution with a pH of 5?
Lower pHs are more acidic Higher pHs are more basic. Therefore, the pH of 5 will be more acidic than pH of 7 ** also, the pH of 7 is neutral. Edit by Kelvin876: Higher pHs are alkalines. **Each number lower is 10 times greater in acidity than the prior number. This would mean that a solution with a pH of 5 is 100 times greater in acidity compared to a solution with a pH of 7.
Why are porcelain insulator made brown in color?
Fist off, modern porcelain insulators are typically gray in color, however, prior to the 1960's porcelain insulators were all manufactured to be brown in color. Then, during the president Johnson era, first lady, Lady Bird Johnson initiated a "Beautification Campaign" across America. This included planting trees, removing billboards along the sides of highways and giving the United States power system a more modern look. Thus, a general gray color was instituted for new power construction, this including the porcelain insulators that were attached to electrical towers. If you look closely at older transmission and distribution lines, you can sometimes see these older brown insulators.
How do you use citric acid for cleaning?
Citric acid is good for certain kinds of cleaning, but not all. Citric acid is particularly effective in the removal of scale on shower heads, faucets, and coffee makers. It can also be used as a pre-cleaner for garage floors, prior to coating with epoxy paint. When used for cleaning, citric acid is always dissolved in water first. The concentration depends on the application. A solution of 100 g citric acid (roughly 4 ounces) in 1 liter (roughly a quart) of water will make an excellent descaling solution.
