Some true statements regarding pH include, the pH scale indicates concentrations of hydrogen and hydroxyl ions in a solution. Anything above a pH level of 7.0 is basic, anything above a 7.0 is acidic, and a change in one pH unit denotes a ten-fold increase or decrease in hydroxyl ion concentration.

The paired statements in a dichotomous key must be opposite in order to present two mutually exclusive choices that lead to the correct identification of an organism. This system helps users narrow down the possibilities at each step until reaching the correct classification.
The reason pure water is considered neutral with respect to pH is because?
pure water has an equal concentration of hydrogen ions (H+) and hydroxide ions (OH-), resulting in a pH of 7. This balance of ions makes pure water neither acidic nor basic, hence its classification as neutral on the pH scale.
How does pH affect enzyme functions?
Enzymes lower the amount of Activation Energy needed for a chemical reaction, therefore speeding up the chemical reaction. For an enzyme to do this it needs to be at the correct pH, salinity, and temperature otherwise the enzyme will not be able to work. When an enzyme is in a pH that is not suitable, the enzyme's shape and structure alter and make it unable to speed up a reaction.
What is the optimum pH range of enzymes?
The correct pH range is + or - 0.5 of the optimum pH as the enzyme will often denature at pH's outside this range. The optimum pH varies from enzyme to enzyme as each one has different optimum conditions.
What statement about the treatment of slaves is NOT correct?
There are many statements about the treatment of slaves that are not correct. For instance it would not be true to say that slaves got preferential treatment from their masters.
What statements about language acquisition are correct?
all answers are correct
What pH is best to be used?
Correct the pH if it falls below 7.2 or rises above 7.6. Correct pH will ensure the chlorine is working effectively.
Difference of pH of 12 and pH of 13?
Something with a pH of 12 is exactly 10 time more acidic than something with a pH of 13. Or you could say the opposite that something with a pH of 13 is 10 times more basic(is a base) than something which has a pH of 12 which would make more sense to say because everything above a 7 is a gradually stronger base (or alkaline) which neutralizes acid. However both statements would be correct.
