the pH scale is used to show how acidic or basic a substance is... you usually use red or blue litmus paper, and then using the label that comes with the paper, figure out how acidic or basic it is using the scale on the bottle, and the pH scale.
indicates the concentration of H+ ions in a solution

∙ 14y agohoe acidic or basic a substance is 0-14 scale 7 is neutral like water
pH indicates potential hydrogen weak acid, strong acid, neutral, weak alkali and strong alkali. Acids are pH 1-6, Alkalies are pH 8-14 in some peoples case 11. pH 7 is neutral.
Acids can be from dark red to light orange to brown.
Alkalies can be from blue to purple, going from light to dark gradually.
Neutral should always be green.

∙ 14y agoThe pH scale indicates how acidic or basic a substance is. Pure water is neutral and has a pH of 7.0. All acids are below 7.0 and all bases are above 7.0 pH.

∙ 15y agop = -log
H= concentration of hydrogen in solution (H+)
therefore,
pH= -log [H+]
or
[H+] = 10-pH

∙ 15y agoThe strength of acids and alkalis. pH 1 indicates a strong acid and pH6 a weak acid. pH 8 indicates a weak alkali, pH 14 a strong alkali. pH 7 is neutral

3 How is the Universal indicator color chart used to measure acidity?
We measure pH by using a pH scale which has different colours on it which indicates the liquid. Universal indicator is a pH indicator that transitions through numbers 1- 14 (on a pH chart) to indicate the acidity or alkali of solution. A pH meter is an electric instrument used to measure the pH of a liquid which might be an acid neutral or an alkali. and there is my answer Lewis Jones park community school lots of substances change colour at specific pH values, so you have to use a colour chart for that specific substance. Universal indicator is a mixture of lots of different indicators so it changes colour many times throughout the entire pH range, and you can compare it to the universal indicator colour chart to find how acidic or alkaline your substance is.
A substance with a pH of 11 is what times more what than a substance with a pH of 8?
A pH of 11 is 1000x more alkaline than a pH of 8. The pH scale is a logarithmic scale. This means that in a pH scale, a change of one whole number represents a tenfold change in the pH. So a pH of 8 is 10x more alkaline than a pH of 7.
What does 7 indicate on the pH scale?
The pH scale goes from 0 to 14 where 7 is neutral. 0 is the most acidic possible, and 14 is the most base.
What is a substance with a pH of 6?
The pH scale runs from 0 to 14. Pure water has a pH of 7, the half-way point of the pH scale. A pH between 0 and 7 indicates that a solution is acidic, and the lower the pH, the higher the acidity. A pH between 7 and 14 indicates that a substance is alkaline, and the higher the pH, the higher the strength of the alkali.
Does the pH of the medium change during sterilization?
yes. The PH will changer We have to adjust the pH after sterilization by filtration
What does the pH number indicate about a fuel sample?
pH is an indication of acidity.
What is does the pH do as nutrition?
Nothing. pH values indicate acidity levels.
What does a 7 on the pH scale indicate?
pH=7 is the neutral point on the scale.
What does your data indicate about the optimum pH level for this lactasecatalyzed reaction?
PH 9
What does pH value of 6.46 indicate?
BASE
What does pH 7 indicate?
pH 7 is at the center of the pH scale. It means the solution is neither basic nor acidic. Water has a pH of 7.
What is the scale used to indicate the strength of an acid or base called?
pH Scale
What does a 1 on the pH scale indicate?
Massive acidity.
High pH levels indicate what?
A basic solution.
During digestion the pH in the stomach is 2 What does this indicate about the optimum pH of pepsin?
Pepsin is therefore acidic since the pH in the stomach is 2
Does a pH of 12 indicate a strong or weak base?
pH =12 is a very strong base. The high value pH is #14#.
Is paper of vniversal pH paper indicate 7?
