Acid has a ph of 7<

One of the properties is that both acid and alkali are corrosive. Acid turns red on a litmus paper while alkali turns blue.

Shah

Acids contain hydrogen ion H^+

Fatin

2016-06-28 05:05:32 UTC

One of the properties of acids is that it dissolve in water to form solutions which conduct electricity.

Dylan

Acid turns red on blue litmus paper while Alkali turns blue on a red litmus paper.

acid + base ---> salt + water

Aidil

Acid <7 ph level
Neutral 7 ph level
Alkali >7 ph level

I want to learn more about acid and bases and how we

Audrey

2016-06-28 05:08:36 UTC

acids turn blue litmus paper red

Hendra

2016-06-28 05:08:38 UTC

I want to learn the the different types of reaction.

Sabrina

2016-06-28 05:08:40 UTC

Acid is sour while alkaline is bitter

Kai Ming

2016-06-28 05:09:14 UTC

Alkaline taste bitter

Audrey

2016-06-28 05:09:20 UTC

How else can we use acids and bases

Aidil

2016-06-28 05:09:41 UTC

I want to learn more about other uses of acids

Kai Ming

2016-07-07 04:57:37 UTC

I have learn that most bases are insoluble in water.

Chen Yee

2016-07-07 04:57:39 UTC

Base + Acid->salt +water

Aaron

2016-07-07 04:58:12 UTC

I have learnt H+(aq) + OH-(aq)=H2O(l)

Irna

2016-07-07 04:58:17 UTC

Common alkalis:
*1. NaOH (aq)
*2. KOH (aq)
3. NH4OH (aq)

Nica

2016-07-07 04:58:58 UTC

all alkalis are bases but not all bases are alkalis.

Atiqah

2016-07-07 04:59:00 UTC

All alkalis are bases but not all bases are alkalis.Bases that are not alkalis are bases that cannot dissolve in water.

Gladys

YY 1. I learnt the common typeof alkalis like sodium hydroxide (NaOH) and potassium hydroxide (KOH).
2. I also learnt about the uses of bases and alkalis such as ammonium hydroxide which is used for making fertilisers.

Jiaxin

Use of Bases
- Magnesium oxide can be used to relieving gastric pain and for making refractory bricks.

Aidil

2016-07-07 04:59:33 UTC

Alkali is a base that is soluble in water

Dylan

2016-07-07 04:59:34 UTC

I have learnt that a base is any metal oxide or hydroxide that reacts with an acid to produce a salt and water , this process is called neutralization.

Nada

2016-07-07 04:59:57 UTC

I have learnt that one of the uses of magnesium oxide is to relieve gastric pain.

Hendra

2016-07-07 05:00:00 UTC

Alk-Ali reacts with acids to form salt and water , this reaction is called neutralisation.

Audrey

2016-07-07 05:00:01 UTC

I've learn that base + acid = salt+water

sivani

Alkalis turns red litmus paper red

Givari

2016-07-07 05:06:47 UTC

Acids are important

Givari

2016-07-07 05:09:56 UTC

Alkali produces OH minus ions when dissolved in wataa

Gladys

2016-07-07 05:10:14 UTC

I have learnt about the common types of alkalis like sodium hydroxide ( NaOH) and Potassium Hydroxide (KOH).
2. I have learnt about the uses of bases and alkalis such as ammonium hydroxide for fertilisers.
3. I have also learnt that when alkalis reacts with metal salt, it will produce salt and metal hydroxide.
