Does the addition of water (baking soda plus water) alter the pH of weak acidsbasesHow does it changethe pH of srong acidsbases Why or why not?
The addition of water to weak acids or bases generally dilutes the solution, which can lead to a slight increase in pH for weak acids and a decrease in pH for weak bases due to the equilibrium shifting. In contrast, adding water to strong acids or bases typically results in a more significant change in pH, as strong acids and bases dissociate completely in solution. Therefore, dilution with water for strong acids will lower the pH (less acidic) and for strong bases will raise the pH (less basic) but will still remain strongly acidic or basic depending on their original concentration. Overall, the extent of pH change depends on the strength and concentration of the acid or base involved.
How can you tell how strong acids and alkalis are using the pH scale?
Acids have a pH under 7, alkalis have a pH bigger than 7.
The pH of a strong base would be closest to?
The pH scale is from 1-14 Strong acids are 1-4
The metabolic processes usually adds acids or bases to the blood?
Metabolic processes can add acids (such as lactic acid or ketones) or bases (such as bicarbonate) to the blood. The balance between these acids and bases is crucial for maintaining the body's pH within a normal range. Imbalances in these processes can lead to conditions like acidosis or alkalosis.
Which solutions showed the greatest change in pH why?
The solutions that showed the greatest change in pH are typically those with strong acids or strong bases, as they fully dissociate in water, leading to a significant increase or decrease in hydrogen ion concentration. For example, adding hydrochloric acid (HCl) to water will dramatically lower the pH, while adding sodium hydroxide (NaOH) will raise it significantly. Additionally, buffers may show less pH change because they resist alterations in pH due to the presence of weak acids or bases that can neutralize added acids or bases.
Does strong acids tend to raise pH?
No, strong acids tend to lower the pH of a solution. This is because strong acids donate hydrogen ions (H+) when they dissolve in water, increasing the concentration of H+ ions and lowering the pH.
Which has a lower pH weak acids or strong acids?
pH = 0 to 2 is a STRONG acid. ( e.g. Hydrochloric Acid) pH = 3 to 6 is a WEAK acid. ( e.g. Ethanoic (Acetic) acid). NB THe greater the numerical value of the pH , then the weaker the acid.
What is the lowest pH to the highest pH?
Lowest pH, strong acids, then weak acids, then salts of strong acids and strong bases, then salts of weak acids and strong bases, then weak bases, then strong bases. All very confusing!
What is the ph value of acids?
1-6 1- Strong Acids 6- Weaker Acids
Would you expect strong acids or weak acids to have a lower pH level?
Strong acids would be expected to have a lower pH level compared to weak acids. Strong acids fully dissociate in water to produce a higher concentration of hydrogen ions, resulting in a more acidic solution and a lower pH.
Do strong acids have a higher or lower pH than weak acids?
Strong acids have a lower pH than weak acids. This is because strong acids completely dissociate in water to release all their hydrogen ions, resulting in a high concentration of H+ ions and a lower pH. Weak acids only partially dissociate, leading to a lower concentration of H+ ions and a higher pH.
What colour on the ph scale will show strong acids?
Strong acids will appear at the lower end of the pH scale, typically around 0 to 3. The color associated with strong acids on pH test strips is typically a bright red to indicate the low pH levels.

Are weak acids on the pH scale less than 3?
NO!!!! The pH scale is from 0 to 14. The lower the numerical value of the pH , then the stronger the acid. e.g. pH = 1 Strongly acidic ( e.g. Hydrochloric Acid). pH = 4 Weakly acidic ( e.g. Ethanoic (Acetic) acid). pH = 7 Neutrality (Water) pH = 9 Weakly Alkaline ( Ammonia Solution). pH = 12 Strongly Alkaline ( Sodium Hydroxide). pH = 14 Very strongly alkaline ( very weakly acidic ; in extremis). NB The pH is the 'negative logarithm , to the base 10, of the hydrogen ion conc'n. Algebraically ; pH = -(log(10)[H^(+)]) The inverse maths. function is [H^(+)] = 10^(-pH). So if you have a pH = 1 Then H^(+) = 10^(-1) = 0.1 ( Casually a tenth of the sol'n is hydrogen ions). If you have a pH = 12 Then H^(+) = 10^(-12) = 0.000000000001 (Casually a trillionth of the solution is hydrogen ions; usually considered as strongly alkaline with a pOH = 0.01, an hundredth of the solution is hydroxide ions, compared to a trillionth( an extremely tiny amount), of hydrogen ions.
Renal tubules can raise blood pH?
Renal tubules can raise blood pH primarily through the reabsorption of bicarbonate (HCO3-) and the excretion of hydrogen ions (H+). When bicarbonate is reabsorbed in the proximal tubule, it helps neutralize acids in the blood, thereby increasing pH. Additionally, the secretion of hydrogen ions into the urine allows for further regulation of acid-base balance, contributing to a higher blood pH. This process is crucial for maintaining homeostasis in the body's acid-base balance.
