Question

Why would it be difficult to
test the pH of orange juice
with universal indicator?​

Answer 1

BEFORE WE GET INTO THIS LET ME EXPLAIN YOU WHAT IS pH

SO BASICALLY IT IS scale used to specify the acidity or basicity of an aqueous solution..

Now let's come to your answer- Orange juice has a pH of 4, indicating it's more acidic than neutral. The Universal Indicator paper would turn a color ranging from orange to yellow depending on the particular brand of test strips.

let me explain you in detail-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.
