Answer
In an alkali, red litmus paper transitions into the color blue.
Explanation
## Step 1: Understanding the concept of litmus paper:Litmus paper is a testing resource in chemistry that is used to determine whether a substance is an acid (exhibiting a higher total number of hydrogen ions) or a base (depicting fewer hydrogen ions). Within the breadth of acidity to basicity, substances can be further classified into the broad band of "alkaline" or "basic" substances when they register a higher pH scale number (>7).## Step 2: Understanding the behavior of red litmus paper:Undergoing modification by an alkali (or basic substance), red litmus paper changes its color from its default remotest radiant red.
