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
What else can I help you with?
Which of these statements is correct with respect to pH?
Some true statements regarding pH include, the pH scale indicates concentrations of hydrogen and hydroxyl ions in a solution. Anything above a pH level of 7.0 is basic, anything above a 7.0 is acidic, and a change in one pH unit denotes a ten-fold increase or decrease in hydroxyl ion concentration.
What is meant by the term alkalinity?
Alkalinity refers to the ability of a solution to buffer against changes in pH when an acid is added. It is a measure of the concentration of alkaline compounds, such as bicarbonates, in the solution. Higher alkalinity levels indicate greater resistance to pH changes.
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.
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.
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.
Is a solution with a pH 6 an acid or a base?
A solution with a pH of 6 is considered acidic. pH values below 7 indicate acidity, while pH values above 7 indicate alkalinity.
Using the pH scale what numbers indicate an acid What numbers indicate a base?
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.
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 a low pH indicate in a solution?
A low pH in a solution indicates that it is acidic.
What does pH value of 6.46 indicate?
BASE
What pH would indicate and acidic soil?
The answer to 'What pH would indicate and acidic soil?' is 5. 5 is a week number and 1 is the strongest, 7 is neutral and 14 is a strong alkali 9 is week.
What does a high pH indicate in a solution?
A high pH in a solution indicates that the solution is basic or alkaline.
What does a low pH indicate about the acidity level of a substance?
A low pH indicates that a substance is acidic.
What does a negative pH indicate in a solution?
A negative pH in a solution indicates that the solution is highly acidic.
