What is the effect of phenopthelin on bases?
Phenolphthalein does not directly interact with bases. It is a pH indicator commonly used in titrations to determine the endpoint of an acid-base reaction, where it changes color depending on the pH of the solution. It remains colorless in acidic solutions and turns pink or purple in basic solutions.
What is the formula to calculate pH slope?
The formula to calculate pH slope is ΔpH/Δlog[H+], where ΔpH is the change in pH and Δlog[H+] is the change in the log concentration of hydrogen ions. This formula is used to determine the sensitivity of a pH electrode.
What is the base chemistry formula for determining the pH of a solution?
The base chemistry formula for determining the pH of a solution is pH -logH.
Formula for calculation pH and pOH?
pH + pOH =14
What is the formula for getting pH?
pH = pKa + log([A-]/[HA])
What is the Logarthimic formula to get PH level of water?
pH is the negative log of the hydronium ion concentration. It seems a little grandiose to call this a "formula", but here you go: pH = -log[H3O+]
Give an example of logarithmic formula that give the pH of a substance?
pH=-log(H+)
What is the chemical formula of trypan blue?
what is the chemical formula for thymol blue
What is the formula for a cube?
S=ph+2b
What is the formula of calculating pH?
pH = - log [H3O+]. It is the negative logarithm of the hydronium ion concentration.
What is pH of ethylene glycol?
Molecular formula is C2H6O2 Maybe pH is 7. I measure the PH of ethylene glycol myself with az 8686 PH meter. The number that i saw was 8. I thinck its because of hydroxyl group(OH) in its Molecular formula(HOCH2CH2OH=C2H6O2).
What formula is used to find pH?
-log [h30+]
