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.
Buffers are chemicals that do all of the following except keep pH within certain limits?
Buffers are chemicals that help maintain a stable pH by neutralizing excess acids or bases in a solution. They work by either donating protons (H⁺) when the solution becomes too basic or accepting protons when it becomes too acidic. However, buffers do not completely prevent changes in pH; they only limit fluctuations within a certain range. Therefore, the statement that buffers keep pH within certain limits is true, but they cannot guarantee absolute pH stability.
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.
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.
How is the pH scale similar to the Richter scale?
Both the pH scale and the Richter scale are logarithmic. A decrease of 1 on the pH scale means a tenfold increase in acidity while an increase of 1 on the Richter scale means a tenfold increase in intensity.
