Question

There are five solutions M, N, X, Y and Z. Out of five, three are indicators and two are either acid(s) or base(s). Following statements are some observations Yashi carries out to find out the chemical nature of these solutions.
(i) Shampoo and N mixed than a solution of colour changes to red
(ii) M and N mixed the colour of solution changes to yellow
(iii) M and Y mixed then the colour of the solution changes to green
(iv) X is yellow and Y is pink
(v) X and Z mixed then the colour of the solution remains yellow
Which of the following is the correct sequence for solutions M, N, X, Y and Z



Acid, methyl orange, turmeric, china rose, acid

Base, methyl orange, turmeric, china rose, bases

Base, turmeric, methyl orange, china rose, acid

Base, methyl orange, turmeric, china rose, acid

Answer 1

Answer 2

The following question can be answered as follows:

• Certain types of indicators are used to identify the chemical nature of a solution. Some of the chemical and natural indicators used are as follows:

1. methyl orange - it turns yellow in basic medium and dark red in acidic medium
2. China rose - turns green in basic solution and magenta in acidic solution
3. Turmeric - remains yellow in acidic solution and turns red in basic solution.

• Based on the given statements, we can conclude the following:

1. A shampoo is slightly acidic with a ph of 3.5 - 5.5, thus N can be identified as methyl orange.
2. M can be identified as a base since the color remains yellow when it reacts with methyl orange
3. Y can be identified as a china rose indicator since it turns green on reaction with M which is a base
4. X is turmeric since it is yellow.
5. Z is an acid since the color remains yellow after the reaction with turmeric.

Thus, the solutions can be identified as:

1. M - Base
2. N - Methyl orange
3. X - Turmeric
4. Y - china rose
5. Z - acid

Hence, (Option 4) Base, methyl orange, turmeric, china rose, acid are the correct answer.
