Yes. All rational numbers can be changed into fraction form, while all numbers that can't are irrational.
All numbers of the form 10710*k where k is an integer.
10
All numbers of the form 855*k where k is any integer.
Rational numbers form a proper subset of real numbers. So all rational numbers are real numbers but all real numbers are not rational.
Numbers below 7 on the pH scale represent acids, with lower numbers indicating stronger acidity. A pH of 0 is the most acidic on the scale.
The pH is under 1.
This pH is near 14.
pH numbers below 7 indicate an acid, with lower numbers indicating stronger acids. pH numbers above 7 indicate a base, with higher numbers indicating stronger bases.
pH numbers range form 1 (highly acidic) to 14 (highly basic) 7 is neutral. Any number higher than 7 indicates a base.
Its when you add all the numbers together
pH values are indications of acidity/alkalinity of a solution.
Neutrality is a pH=7,00.
The pH number will determine if the liquid is acidic or alkaline.
On the pH scale, acids have a pH of less than 7.
The pH value is a measure of the acidity/basicity of a solution.
The numbers 7.1 through 14 are the basic numbers.
