What can tell us whether something is an acid or alkali in 10 letters?
Test the pH.
Why is an indicator a valuable tool for measuring pH?
Most acidic solutions and basic solutions are colourless and transparent. Therefore, you cannot tell the difference between an acid and a base by appearance alone. One safe way to determine wether something is an acid or a base is to use an indicator.
What is the best way to determine whether a substance is an acid or base?
A pH meter gives a direct reading which is great when testing wine or soft drinks. Litmus paper will go red in acid or blue in base. An acid will liberate carbon dioxide from chalk - a base will not You cook a red cabbage and save the juice. then if the thing you are testing turns red in the juice, it is acidic, if blue basic. Turmeric indicates acid by turning strong yellow. Base is indicated by red. Phenolphthalein indicates bases by turning red or purple. Acid is indicated by no color.
How can you tell an acid or base or neither from a chemical formula?
There is no hard and fast rule that can determine an acid/base solely from the formula. Some can be derived from knowing the electronegativities and bonding behaviour of the elements concerned; some can be determined from knowing the electronic configurations of the elements; some can be told simply from memory i.e. if you know it's an acid/base then it's an acid/base. Some cannot be derived at all from the formula; amphoteric substances for example, will be either basic or acidic depending on the conditions, and some substances will only act in certain ways in certain conditions too.
How can you tell an acid from a base?
You can tell by testing it with either universal indicator solution or with litmus paper.There are other methods, but some of them are not exactly safe: acids usually taste sour (do not try this) and bases usually taste bitter (do not try this either). Also, bases tend to feel "slippery" (at the risk of sounding like a broken record, do not try this).
How can you tell if something is a acid or base without testing?
An acid tastes sour, and a base is bitter
Can something be an acid and a base?
you get red and blue litmus paper and put it in the liquid and it'll tell you if acid,base,or neutral
How can you tell if something is a acid or base?
A PH meter or litmus paper.
Is washing powder an acid or a base?
Yes, it is. You can tell weather something is an Alkali, Neutral pr acid via the pH scale or, you can tell if something is an alkali from its consistency; if it is sludgy (like washing-up liquid), it is an alkali. So, I am under the influence that washing-up POWDER is too, an alkali.J.S.P. Aged 11
How can you tell if something is an acid or alkali?
be quit
How can you tell on acid from a bace?
Using an indicator.
Is CaSO4 an acid or a base?
CaSO4 is neather acid or base it is a salt which means it is nutreal.
What can litmus paper tell you about a solution?
Litmus will allow you to tell if a solution is a acid or a base.
Is it weak acid or strong acid when the position of a reaction lies to the left?
you cant really tell if its strong like that. you need indicator liquid to tell you if its an acid or a base and then tell if its strong by seeing the reaction.
How can you tell if a food contains an acid or a base?
If its acidity level is below 7, then it is a acid. If it is above a seven, then it is a base. If it is exactly 7 then it is neutral such as water.
What is the evidence of the completion of reaction between acid and base?
Please tell me
What does the universal indictor tell you about material?
Its pH and if a solution is an acid or base.
