To clean your pure wool sweater, it is best to hand wash it in cold water using a gentle wool detergent. Gently agitate the sweater in the water and then rinse it thoroughly with cold water. Avoid wringing or twisting the sweater as this can cause it to lose its shape. To dry the sweater, gently press out the excess water and then lay it flat on a clean towel to air dry. Avoid hanging the sweater as this can cause it to stretch out of shape. Once the sweater is dry, you can gently steam it to remove any wrinkles. **

Dry indicator paper does not change color in pure hydrochloric acid because the paper needs to be moist in order for the indicator to react with the acid. The indicator on the paper is typically a weak acid or base that changes color when it reacts with an acidic or basic solution. In the absence of moisture, the indicator cannot undergo the necessary chemical reaction to change color. Therefore, the dry indicator paper remains unchanged in pure hydrochloric acid. **

Dry indicator paper shows no color change in pure hydrochloric acid because hydrochloric acid is a strong acid and does not contain any water molecules to participate in the acid-base reaction with the indicator. Indicator papers rely on the presence of water to facilitate the acid-base reaction and produce a color change. Since pure hydrochloric acid does not contain water, the indicator paper does not undergo a color change. **
