Soap does not turn water blue. It is likely that a blue-tinted soap was used, or that the soap contained a dye or pigment that resulted in the blue color when dissolved in the water.
When blue litmus paper is placed in soapy water, it remains blue because soap is typically alkaline (basic). Litmus paper is used to test pH levels, and blue litmus paper indicates a neutral or basic environment. If the water were acidic, the blue paper would turn red, but in this case, the soapy water keeps it blue.
The Ph scale is from 0-14. 7 is neutral. So, 9 would be increasing to alkaline. below 7 is acidic. Red litmus paper would turn blue in soapy water, and blue litmus paper would stay blue. Soapy water is a base.
A microwave oven is designed to heat water, or substances which contain water. It does not work well for substances that do not contain water, and that includes soap. However, you could put the soap in water in a shaving mug, and the water could be made hot enough to melt the soap.
Soap is typically basic in nature, so when it comes into contact with blue litmus paper, it can turn the paper from blue to red. This color change occurs because the soap's alkaline properties react with the litmus dye, causing it to change color.
The litmus papers are used for checking the acidic and basic nature of any substance. That's why drop of lemon juice, which is by nature acidic, turns blue litmus into red(as the property of acidic solution is to change the color of blue litmus to red). So soap solution which is by nature basic will turn red litmus into blue (as the property of basic solution is to change the color of red litmus to blue).
soap is basic therfore, soap solution will keep blue litmus paper blue and turn red litmus paper blue
When red litmus paper is added to soap solution, it will turn blue. This indicates that the soap solution is alkaline in nature, as alkaline substances turn red litmus blue. This is because soap solutions typically have a pH above 7.
Soap powder typically turns a pH indicator such as litmus paper to blue or purple, indicating that it is basic or alkaline in nature.

If blue litmus paper is dipped in a soap solution, it is likely to turn red. This change in color indicates that the soap solution is likely acidic in nature.
Dish washing soap may turn blue or purple when universal indicator is added, indicating it is basic.

Soap solution can be basic or acidic, depending on the composition of the soap. In general, a soap solution would likely be basic, which would turn pink/red in the presence of a pH indicator like phenolphthalein or blue/green with bromothymol blue.
The Ph scale is from 0-14. 7 is neutral. So, 9 would be increasing to alkaline. below 7 is acidic. Red litmus paper would turn blue in soapy water, and blue litmus paper would stay blue. Soapy water is a base.

When washing dishes, turn off water when using soap. Also you can turn off water while brushing teeth, when you rinse, then you can uses the water.
