What else can I help you with?
What limits the pH of the solution?
The concentration of H+ or OH-.
What are intervals of pH?
Intervals of pH represent ranges of acidity or alkalinity. For example, pH 0-6 is acidic, pH 7 is neutral, and pH 8-14 is alkaline. These intervals help in categorizing substances based on their level of acidity or alkalinity.
What are the characteristics of a buffer system?
Buffering system is the physiological system that function to keep pH within normal limits.
What is a non- example of a pH scale?
A non-example of a pH scale would be a temperature scale, such as Celsius or Fahrenheit. While the pH scale measures the acidity or alkalinity of a solution, temperature scales measure thermal energy. Additionally, a scale measuring weight, like pounds or kilograms, is also a non-example, as it pertains to mass rather than chemical properties.
The action of a buffer to maintain pH with normal limits consists primarily of?
One kind of burref contains a weak acid with one of its salts. The limited amount of ionization of the weak acid is kept nearly constant due to the presence of the salt. As the acid is neutralized a small amount of unionized acid will form more ions (Le Chatlier's principle of equilibrium) will ionize to replace the H+ ions and keep the pH nearly constant.
What colour is copper sulphate on pH scale?
Copper sulfate appears blue in color on the pH scale.
What limits the pH of the solution?
The concentration of H+ or OH-.
How is pH scale different from other scales of measurement like the Fahrenheit temperature scale?
pH is a logarithmic scale, so a change of 1 in pH means a change of 10 in the quantity. It is also negative, so as pH increases the measured quantity actuallly goes down. The temperature scales are simply direct scales; all changes mean the same thing and going up means going up.
What pH colour is lemon juice?
Lemon juice is acidic with a pH around 2.0-2.5, which is typically indicated by a yellow color on pH test strips or scales.
How do manufacturers determine the limits for the calibration of scales and balances?
I assume you mean the manufacturer while making and selling scales and balances. By the specifications on the equipment they are selling.
Why do semi's need to stop at weight stations on the highway?
All commercial trucks are subject to total vehicle weight limits and also weight limits per axle. The scales are there to enforce these weight limits.
What are compounds that in solution maintain pH within given limits?
Buffer solutions are compounds that in solution maintain pH within given limits by resisting changes in pH when an acid or base is added. Buffers typically consist of a weak acid and its conjugate base, or a weak base and its conjugate acid, which help stabilize the pH of the solution.
The strongest base would have a pH of?
Practically pH of 14 or 15 is the highest base value reachable, due to limits of max. concentration.
Substances which maintain a body's pH within narrow limits are called what?
Buffer solutions are substances that help maintain a body's pH within narrow limits by resisting changes in pH when small amounts of acid or base are added. Buffers are able to absorb excess hydrogen ions or hydroxide ions to prevent drastic changes in pH levels.
What are some common logarithmic scales?
The Decibal scale for sound measurement is an example of a logarithmic scale. The Richter scale, the pH scale, the magnitude scale for stars, the multiplicative scales on a slide rule
What are intervals of pH?
Intervals of pH represent ranges of acidity or alkalinity. For example, pH 0-6 is acidic, pH 7 is neutral, and pH 8-14 is alkaline. These intervals help in categorizing substances based on their level of acidity or alkalinity.
Strongest base a pH can have?
Practically pH of 14 or 15 is the highest base value reachable, due to limits of max. concentration.
