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.
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.
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.
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
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.
Why is the range of pH fixed?
pH is a function of the concentration of hydronium ions in a water solution and theoretically can take any number, not just the traditional 1-14 range. However there are physical limits to how much of this substance can be present in a solution without precipitating and this establishes the lower limit of pH. At the other end of the scale pH can be determined mathematically from the concentration of hydroxide ions, but this too is limited to a point, setting the upper limit for pH. These limits take the allowable pH range down to about -5 and up to perhaps 20.
