pH value 1 represents a solution with the lowest OH⁻ion concentration.
<u>Explanation:</u>
pH is given by the expression as the negative logarithm to the base 10 of the concentration of hydrogen ions.
pH = -log₁₀[H⁺]
If the pH is lower than 7, pH < 7 then it is acidic
If the pH = 7, then it is neutral
If the pH > 7, then it is basic
If pH is 1 then the solution is showing mostly acidic character,which is least basic in its character.
So if the pH is 1, which is most acidic and least basic solution that is lowest OH⁻ ion concentration.
Answer:
A
Explanation:
Both suspect A and the note has the same number of spots.
Answer:
A decompositon reaction is a reaction that takes place when one reactant breaks down into two or more simpler substances. The decomposition reaction can be represented by the general equation: AB → A + B. Most of the decomposition reactions require an input of energy in the form of heat, light or electricity
Explanation:
Answer:
B. It showed that microorganisms bring about chemical changes
Explanation:
In 1857 Pasteur was working to solve a problem with the distillers of Lille in wich in their barrels the alcoholic fermentation become in a lactic fermentation, and of course, that was something that they didn't want. Throughout diferents studyes Pasteur discover that different microorganism where involved directly (where responsible) in different types of fermentation. That was the key to start the microbiology studies worldwide.
