Why is it very difficult to measure the pH value of blackcurrant juice with universal indicator?
Wiki User

because it as actually an indicator not a solution

∙ 11y agoIt is difficult because Orange Juice consists of different solutions such as water and acid so the juice would have to be separated to find the pH of the acid inside the juice.
Wiki User
∙ 12y agobecause you cant always be certain as there are only 12 which is a quite small number, that is wht i think but i think you shud try other websites to make sure :)) hope theat helped, Victoria K XD :) :p
Wiki User
∙ 11y agobecause there are 14 values which is a small number
Wiki User
∙ 13y agoUnless it can be dissolved then basically yes.
Wiki User
∙ 7y agoBecause the blackcurrant juice has a very intense color.

What is the difference between an indicator and a universal indicator?
A pH meter uses a probe and voltmeter to measure pH digitally. Universal indicator is a mix of indicators that change colour to indicate the pH of the solution. pH meters are accurate and will detect changes quickly, whereas universal indicator is slow to change colour to indicate pH change.
What do you use to measure pH level?
An indicator of some sort
Why is a universal indicator better than a litmus?
coz universal indicator tells you whether its a strong or weak acid or alkali but litmus paper only tells you whether the sunstance is acid (red) or alkali (blue)
How we measure the pH of body fluids with pH paper?
ph-indicator strips (colorpHast)
The purpose of an indicator in a titration experiment?
The indicator is used to measure the end point of titration. Methyl red and phenolphthalein are frequently used indicators in acid-base titration. Potassium permanganate can used as a self indicator in redox titrations where applicable.
Describe how you would measure PH of an unknown liquide?
Add universal indicator.
How do scientists measure food pH?
Through using the universal indicator or the PH probe.
Why is universal indicator a valuable tool for measuring pH?
It is a simple and not expensive tool to measure pH.
What is the name of an indicator that measures pH?
Litmus paper goes red or blue in acids or universal indicator may measure some level of pH
Could universal indicator be used to identify a liquid as being pure water?
A pH indicator is used only to measure the pH of the solution.

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.
Why might a scientist prefer to use Universal Indicator rather than a different indicator like litmus?
Litmus only differentiates between acidic and alkaline solutions. It does not give an accurate value of the degree of acidity of alkalinity. Universal Indicator can help measure the pH of the given solution as it does not just change from red to blue and vice versa, but in solution has a range of colours.
Measure the pH of 5 foods in the kitchen using the universal indicator paper and display the foods and their pH?
pH is so stupidd pH is so stupidd
How do you measure the acidity of acid rain?
You add universal indicator and then compare the colour it turns to an example ph scale. The redder the Ui the more acidic it will be, if it is green it will be neutral and if it is blue/purple it will be alkali.
Why is energy difficult to measure?
Why is energy difficult to measure?
Why pH meter to measure the pH of several common household. Can you use a universal indicator or pH paper to measure the pH of all the common household chemicals?
Using a pH-meter the measurement is more accurate and sure.But at home you can use a pH-paper for transparent liquids.
