What best describes an acidic solution?
Acidic solutions are any solution that has a higher concentration of hydrogen ions than water; solutions that have a lower concentration of hydrogen ions than water are called basic or alkaline solutions..
Which compounds are used in batteries check all that apply?
sulfuric acid. lithium hydroxide. potassium hydroxide.
What best describes the pH scale?
The pH of a solution is a measure of the concentration of hydrogen ions in the solution. A solution with a high number of hydrogen ions is acidic and has a low pH value. A solution with a high number of hydroxide ions is basic and has a high pH value. The pH scale ranges from 0 to 14, with a pH of 7 being neutral.

Which substance is a base?
Examples of bases are the hydroxides of the alkali and alkaline earth metals (sodium, calcium, etc.) and the water solutions of ammonia or its organic derivatives (amines). Such substances produce hydroxide ions (OH-) in water solutions (see Arrhenius theory).
What is the pH of milk?
about 6.7 to 6.9Cow’s milk Milk — pasteurized, canned, or dry — is an acid-forming food. Its pH level is below neutral at about 6.7 to 6.9. This is because it contains lactic acid.
Is 9.5 pH water good?
Drinking natural alkaline water is generally considered safe, since it contains natural minerals. However, you should use caution with artificial alkaline water, which likely contains fewer good minerals than its high pH would have you believe, and may contain contaminants.
Is a pH of 14 dangerous?
In terms of pH hydrofluoric acid is considered a weak acid – it does not fully ionize in water – but it is extremely dangerous because of how corrosive it is. … Liquid Drain Cleaner: pH = 14.
What best describes a neutralization reaction?
A neutralization reaction is when an acid and a base react to form water and a salt and involves the combination of H+ ions and OH- ions to generate water.
Which is best antacid?

What is least likely to dissolve completely in water?
Answer Expert Verified. Acetic acid would be least likely to completely dissolve in water.
Which is a strong base?
A strong base is something like sodium hydroxide or potassium hydroxide which is fully ionic. You can think of the compound as being 100% split up into metal ions and hydroxide ions in solution. … Some strong bases like calcium hydroxide aren’t very soluble in water.
What is pH full form?
In chemistry, pH (/piːˈeɪtʃ/, denoting ‘potential of hydrogen’ or ‘power of hydrogen’) is a scale used to specify the acidity or basicity of an aqueous solution. Lower pH values correspond to solutions which are more acidic in nature, while higher values correspond to solutions which are more basic or alkaline.
What pH is dangerous?
The danger of more acidic water – when the pH is less than 6.5 – is that it can leach metals from the well and from the pipes that bring you water. These metals include lead, manganese, copper and iron, and they can be toxic in large amounts.
What is the pH of Coke?
2.52A pH less than 7 is acidic and greater than 7 is basic. Each whole pH value below 7 is ten times more acidic than the next higher value. For example, a pH of 4 is ten times more acidic than a pH of 5 and 100 times (10 x 10) more acidic than a pH of 6….pH Values.PRODUCTpHSodaPepsi2.53Coca-Cola2.52Cherry Coke2.5266 more rows
Is blood acidic or basic?
The pH scale, ranges from 0 (strongly acidic) to 14 (strongly basic or alkaline). A pH of 7.0, in the middle of this scale, is neutral. Blood is normally slightly basic, with a normal pH range of about 7.35 to 7.45. Usually the body maintains the pH of blood close to 7.40.
