The(+) and(-) forms of tartaric acids are .............. .

Explanation

To solve the question, we need to fill in the blank with the appropriate term that describes the relationship between the positive and negative forms of tartaric acid.

### Step-by-Step Solution:

1. **Understanding Tartaric Acid**: Tartaric acid is a naturally occurring organic acid that is classified as a dihydroxy dicarboxylic acid. It has two hydroxyl (-OH) groups and two carboxylic acid (-COOH) groups.

2. **Identifying the Forms**: The question refers to the positive and negative forms of tartaric acid. In chemistry, these forms are often referred to in terms of their optical activity. The positive form rotates plane-polarized light in a clockwise direction, while the negative form rotates it in an anticlockwise direction.
