What pH is a weak alkali?
any concerted alkali is weak alkali
What changes in PH occurs if an alkali is slowly added to an acidic solution?
The actual answer depends on the strength of the acid / alkali used. However the pH will change from around 1-6 to 8-14 depending on the strength of the acid / base. pH ~1 for strong acid pH ~6 for weak acid pH ~8 for strong base pH ~14 for strong base
Is the pH 10 an acid or alkali?
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'.
What is the change in PH when an alkali is slowly added to an acidic solution?
The actual answer depends on the strength of the acid / alkali used. However the pH will change from around 1-6 to 8-14 depending on the strength of the acid / base. pH ~1 for strong acid pH ~6 for weak acid pH ~8 for strong base pH ~14 for strong base
What is the difference between and acid and an alkali?
Acids are substances that donate protons in a chemical reaction, while alkalis are substances that accept protons. Acids have a pH value below 7, whereas alkalis have a pH value above 7. Acids tend to taste sour, while alkalis tend to taste bitter.
Do alkali's have low or high pH's?
High. Acid have a pH of 1-6, neutral (eg water) has a pH of 7 and Alkali's have a pH of 8-14.
Uses of neutralisation other than science?
In agriculture, as soils often contain acidic solutions and plants usually grow best when the soil is slightly alkaline.In medicine, as your blood has a pH of 7.3 and medicine injections must be exactly the same pH. If someone blood is changed by one pH they would die.In digestion, as the stomach is acidic, pH 1 or 2. If we wanted to neutralise the acidity we could swallow an alkaline substance such as sodium bicarbonate.To neutralise bee stings, as bee stings are acidic and can be neutralised using an alkali such as bicarbonate of soda, which would calm the irritation.To neutralise wasp stings, as wasp stings are alkaline and can be neutralised using an acid such as vinegar, which would calm the irritation.To neutralise waste from factories, as if this acidic solution is not treated and ends up in the river it could kill fish. Slaked lime is often used to neutralise the solution as it is an alkali.

What is more acidic pH 1 2 6 7 or 8?
pH 1 is strong acidic pH 7 is neutral and pH 13 is strong alkali

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 the some of the weak acids?
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
What is the pH of indigestion?
As indigestion is caused by acid, the pH value is around 2-4.
What tells us whether something is an acid or an alkali's?
The pH of the solution can tell if it is acidic or alkaline. For acids, pH will be 1 to 7 and for alkaline it will be around 8 to 14. pH of 7 is for neutral solution.
