A weak alkali would have a pH greater than 7 but less than 10. Examples of weak alkalis include ammonia and baking soda.
In weak alkali, universal indicator will typically turn green or blue. The specific color will depend on the pH of the solution - the higher the pH, the bluer the color.
pH = 10 is a moderately strong ALKALI. The pH scale is ;- 1 - 6 ; Strong Acid to weak acid 7 ; water (neutrality) 8 - 14 ; Weak alkali to strong alkali. NB pH only ranges from '1' to '14'.
Moderate. It's pH can vary from 9,5 till 14.
ph 8- p14 is a alkali. blue for weak alkali (ph 8) purple for strong alkali (ph14)
No. Alkali's and acids are an separate ends of the pH scale, the pH of acids being 1, 2, 3, 4 and 5 (strong to weak) and the pH of alkali's being 11, 12, 13, 14 and 15 (weak to strong). Examples of acids are hydrochloric acid (strong) and vinegar (weak). Toothpaste is an example of a weak alkali.
A weak alkali typically has a pH above 7 but less than 10. Examples include baking soda (pH around 8.3) and household ammonia (pH around 10).

The pH of a ripe banana is about 4.5 to 5.2, a weak acid.
its an alkali, the other side of the pH scale you numpty;)
everything is eather an acid or an alkali 1 to 6 on the pH chart are acid 8 to 14 are alkali 7 is newtil
No, bleach is not a weak alkali. Bleach is a strong alkaline substance, commonly sodium hypochlorite, which has a high pH and is used for its disinfecting and cleaning properties.
A weak alkali would typically turn blue or purple in Universal Indicator, indicating a pH around 8-10.
