Question

Marianne gets dressed and puts on some of her favorite perfume. While applying the perfume, she accidentally gets some in her mouth and notices that it has abitter taste. After getting dressed, she heads to the kitchen to prepare some breakfast. She fills a small bowl with plain yogurt and takes a taste. The yogurt is too sour for her liking, so she adds honey to it for some sweetness. When she is done eating, she washes her bowl with soap and water. The soap is so slippery that she accidentally drops the bowl while cleaning it, causing it to break on the kitchen floor. Frustrated, Marianne sweeps up the broken glass and puts it in the trash, and then heads to work. Which substance displays a characteristic of an acid? A:soap B:yogurt C:perfume D:honey

Answer 1

Answer:

Yogurt displays characteristics of an acid.

Explanation:

The characteristics of an Acid are as follows:

• It has an pH of less than 7
• It has a sour aftertaste(though one shouldn't try it)
• It increases the $H^{+}$ concentration of water.
• It reacts with Metals to liberate Hydrogen Gas.
• It gives out $H^{+}$ ions in aqueous solution.
• It turns blue litmus to red.

Only Yogurt displays one of these properties ie. sour taste, therefore it is the only material having characteristic of acid.

Bittery taste and slippery touch are characteristics of bases.
