What do indicators test for?
Indicators are used to test if something for example whether vinegar is an acid or alkali. Due to the pH scale, 1 - 3 is a strong acid, 4 - 6 is a weak acid, 7 is neutral, 8 - 10 is a weak alkali and 11 - 14 is a strong alkali. Vinegar should turn orange when added with an indicator, with the pH of about 3.
What happens to rubidium chloride when added to water?
Rubidium is a large sized atom of alkali metals family and is highly reactive towards water when it is added in water Rubidium hydroxide is formed along with bubbles of hydrogen gas this hydroxide is strong alkali so pH value of water shows a change from 7 to 12 , 13 or 14.
What is a pH scale How do you make a pH scale pls answer FAST?
its something used to see whether a substance is an acid or alkali. the scale is as follows 1-3 is a strong acid 4-6 is a weak acid 7 is neutral (distilled water) 8-9 is weak alkali 10-14 is a strong alkali
What is the hemoglobin level in children?
Newborn: 14-24g/dl; Infant: 10-17g/dl; Child 11-16g/dl.
When alkali metals react with oxygen and form compounds that dissolve in water they produce solutions that are what on the pH scale?
alkali metal + oxygen --> metal oxide metal oxide + water--> metal hydroxide metal hydroxides are strong alkalis, corrosive pH=14
What pH a strong alkali have?
a strong alkali has a strong pH of 11-14. 14 being the strongest.
What is the absolute value of 14 plus and -11?
3
What is the difference between and acid and an alkali?
an alkali is much stronger than an acid because an acid has a PH of 1 and an alkali has a PH of 14.
What is the pH value of a strong value?
11 to 14
What is the median for 14 613 167 11?
The median is 90.5 which is the value halfway between the two middle numbers.
What is the test for an alkali?
You use litmus paper and if it turns dark blue (11 - 14) then it is an alkali, if it turns green (6 - 10) it is neutral, and if it turns red (0 - 5) it's an acid.
What is the pH value of a strong base?
11 to 14
What is alkalis acid?
Alkali isn't an acid. Alkali and acid are terms used when the pH of a substance is a certain number, for example if a substance has a pH of 1, 2, 3, 4, or 5, then the substance is an acid. If the pH is 11, 12, 13, 14 or 15, then the substance is an alkali.
What pH is a weak alkali?
Strong Acid ; pH = 1-3 Weak acid ; pH = 4-6 Neutral ; pH 7 Weak alkali ; pH = 8 -10 ( The answer) Strong Alkali ; pH = 11- 14
Does a strong alkali has a pH of 14?
Yup!! :)) ('.')
Is alkali an acid?
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.
What is a substance that has a pH between 8 and 14 called?
