pH is an indicator of acidity.
A substance registering a pH between 1 & 6 is Acidic (Possibly corrosive).ph of '7' is Neutrality e.g. water.
pH between 8 & 14 is Alkaline ( possibly corrosive).
pH is a logarithmic scale of the level of hydrogen ions in a substance.
Numerically larger the pH , then there are less hydrogen ions present.

A corrosive substance with a pH of less than 7.0 is an acid. Acids have a pH range of 0-6.9 and can cause damage or destruction to living tissues, materials, and surfaces upon contact. Examples of common acidic substances include hydrochloric acid, sulfuric acid, and vinegar.

∙ 12y agoPh is not a substance. It is actually a measurement. Ph is a scale from 1-10, with the lower Ph substances being more acidic, and the higher being more basic (base substances). Water is a 7 on the scale.

Why 70 percent alcohol used in laboratory?
70 percent alcohol is used in laboratories because it has a higher penetrative power than higher concentrations, allowing it to effectively disrupt the cell walls of microorganisms. It also evaporates more slowly than higher concentrations, providing more contact time for disinfection. Additionally, 70 percent alcohol is less flammable and less likely to damage surfaces compared to higher concentrations.
The solution of which substance will hold 70 grams of substance for each 100 grams of water at 30 degrees?
The substance that will hold 70 grams for each 100 grams of water at 30 degrees Celsius is sodium chloride, commonly known as table salt. At this temperature and concentration, sodium chloride is fully soluble and forms a saturated solution.
Which compound is more then 70 percent of the body's tissues?
Water is more than 70 percent of the body's tissues.
Why 70 percent ethanol is used for sterilization instead of 100 percent?
70 percent ethanol is more effective at killing microbes than 100 percent ethanol. This is because the addition of water helps to denature proteins and disrupt cell membranes in the microbes, leading to better penetration and more efficient sterilization. Additionally, 70 percent ethanol is less volatile and evaporates more slowly, allowing for longer contact time with the microbes.
Why only 70 percent alcohol as disinfectant not more or less concentrated?
70% alcohol is considered the most effective concentration for disinfecting because it strikes a balance between killing bacteria and viruses while allowing enough time for the alcohol to penetrate the cell walls. Higher concentrations evaporate too quickly, while lower concentrations are less effective at killing microbes. The 70% concentration also helps to denature proteins and disrupt the cell membrane more effectively.
