Paper is not an alkali; it is a material made from wood pulp. Alkalis are typically strong bases, with substances like sodium hydroxide and potassium hydroxide being common examples. Paper is neutral in nature and does not exhibit the properties of an alkali.
Lithium hydroxide is the strongest alkali in the alkali metal group.
An indicator is a substance that changes color in the presence of an acid or alkali. Common indicators include litmus paper (blue for alkaline, red for acidic), phenolphthalein (colorless in acidic solutions, pink in alkaline solutions), and universal indicator solution (multiple colors to indicate pH level).
Lithium belongs to the alkali metal family in the periodic table.
Technically, yes. EF0 is the weakest, EF1 the second weakest, and EF2 the third weakest. However, Some meterologists consider EF2 and stronger tornadoes as strong, as only about 10% of tornadoes are rated EF2 or higher.
It's challenging to quantify the weakest lightning bolt, as lightning bolts can vary greatly in intensity. However, a "stepped leader" is one of the initial stages of lightning formation and could be considered one of the weakest forms of lightning discharge.

The inside.
pH.paper tells the strength of an acid and alkali and litmus paper tells that whether the substance is an acid or an alkali.
The weakest paper towel is typically one-ply paper towels, which are thinner and have less absorption capacity compared to two-ply or three-ply paper towels. They tear easily and may not hold up well to wet or heavy tasks.
Alkali turns litmus paper blue.
ph 8- p14 is a alkali. blue for weak alkali (ph 8) purple for strong alkali (ph14)
Litmus paper is used to determine if a chemical is acid or alkali. Litmus paper turns red in acidic solutions and blue in alkaline solutions.
blue, indicating a basic pH.
The paper you are referring to is called litmus paper. Litmus paper is a type of pH indicator that changes color in acidic or alkaline solutions, helping to determine whether a substance is an acid or an alkali.
Litmus paper is an indicator that changes color in acid and alkali solutions. In an acid solution, litmus paper turns red, while in an alkali solution, it turns blue.
Every alkali solution above 7 pH at 298 K would turn red litmus into blue.
A red litmus paper turns blue in the presence of a base/alkali, while a blue litmus paper turns red in the presence of an acid.
