An apple (red or other) is a fruit, of which only the 'juicy' part is acidic, like most fruit juices.The 'dry solid' part (fibres, 'flesh', skin etc.) of an apple does not have a pH value, so no acidic or alkaline properties.
pH>7.0
Phenolphthalein is a pH indicator that changes color based on the acidity or alkalinity of a solution. In acidic conditions (pH below 8.2), it is colorless, while in neutral to slightly basic conditions (pH 8.2 to 10), it turns pink. Therefore, when phenolphthalein is added to a solution and the pH changes, the indicator will either remain colorless or change to pink, indicating the pH level of the solution. This property makes it useful in titrations and other chemical analyses to determine the acidity or basicity of a solution.
Granite hasn't a pH.
Red/pink for litmus indicators. Other indicators such as methyl orange will display different colours.
the pH level of a red delicious apple is 6.2
The pH level of a green apple is typically around 3.0 to 3.5, making it acidic.
the pH level of a red delicious apple is 6.2
The pH of apples vary depending on the type and ripeness but usually they have a pH around 4.0.
The pH level of an apple with lemon juice on it is generally around 3, due to the acidity of the lemon juice. Apples themselves are slightly acidic with a pH range of 3-4, but the addition of lemon juice further lowers the pH level.
An apple has a pH level of around 3, making it slightly acidic. A lemon has a pH level of around 2, indicating that it is more acidic than an apple. Both fruits have low pH levels due to their acidic nature.
Granny Smith Apples have a pH of 7.2 to 6.9.
the pH value of apple is 3.60
Natural apple cider vinegar usually has a pH level of about 5 to 7. Any substance with a pH level lower than 7 is considered an acid and anything higher a base, therefore, making it an acid.

A lemon has a lower pH level (around 2) compared to an apple (around 3) due to its higher acidity. The acidity of the lemon allows it to conduct electricity better and light up a light bulb when used in a simple battery setup.
The pH of apple juice is 3. It is an acid.
